Installing a towbar on a VAZ 2107: purpose and step-by-step installation of the device


Every car owner tries to improve his car by changing its characteristics and increasing comfort. If there is a need to transport cargo on a VAZ 2107 whose dimensions do not fit into the luggage compartment, then in this case there is a solution - install a towbar. You can install the product yourself, for which you need to prepare the necessary components and follow the step-by-step recommendations.

    If you ignored the procedure for registering the vehicle trailer (there is no corresponding entry in the registration certificate), an attentive traffic police inspector will sooner or later notice the towbar apron sticking out from behind and ask why it is not properly decorated.

    If you do not receive an intelligible answer, most likely a protocol will be drawn up in accordance with clause 12.05 of part 1 of the Code of Administrative Offenses, which provides for the punishment of this violation with a fine of 500 rubles (making changes to the design of the vehicle that were not approved by the traffic police), which is a violation of clause 7.014 (“Basic provisions for the approval of a vehicle for operation”).

    In addition, the traffic inspector will order you in writing to deliver the car in 10 days to the traffic police for inspection, and if the tow bar is no longer there, everything will only cost you a fine. Otherwise, the registration of the car will be canceled and the state license plates will be entered into the appropriate database, so you will no longer be able to drive such a car. Until the fine is paid and the tow bar is dismantled, after which the registration certificate will have to be restored according to the established procedure.

    If you can convince the inspector that the violation is unintentional, and you take urgent measures to legalize the towbar (or remove it), then he may limit himself to a verbal warning.

    The fine for an unregistered towbar refers to violations subject to the provision of a twofold reduction in the amount if paid within 20 days from the date of receipt of the decision.

    Installation

    We install tinting on a VAZ 2107 ourselves.
    To install a towbar on a 2107 you will need: a drill with a drill, a pair of keys and the help of a friend. After all, you can still mark the holes yourself, but attaching it with bolts will be problematic.

    After all, the VAZ does not have studs for attaching this transport attribute.

    So, having securely secured the towbar, you need to start wiring. After all, the trailer has the same signal lights as the car itself: stops, turns, dimensions, reverse. Its technical condition is subject to the same requirements as the machine itself. Therefore, you should be responsible when connecting headlights. To accomplish this, there are several socket options:

    1. in a plastic case;
    2. in metal.

    Both options are equipped with protective covers that protect the contacts when the trailer is disconnected. A metal case is more reliable and durable, but such a connector will be much more expensive and is most often not included in the kit.

    The tow bar on the 2107 is a great way to expand the functionality of your car. With its help, you can pull a friend’s car out of the mud, you can bring more harvest from the dacha or materials during construction.

    Standard socket connection method


    The trailer has a plug that has 7 or 13 pins.
    It will not always be useful, so motorists use a universal method of connecting the towbar socket. On most domestic cars of the “classic” VAZ 2101-2107 family, the installation of coordination and control units is not provided. Therefore, the socket is installed for a specific trailer. To do this, you only need to know the pinout of the plug. The socket is connected by a wiring harness to the rear light of the car. Before connecting the towbar socket, carefully study the vehicle wiring. The best installation method is to connect the socket to the rear light using plugs. Enough for 7 plugs:

    1. Weight (minus battery).
    2. Left turn signal.
    3. Right turn signal.
    4. Stop signal.
    5. Parking lights.

    And a couple of spare ones wouldn't hurt. In the event of a breakdown, you can quickly transfer the wires from one contact to another. Carefully study the rear light diagram so as not to make mistakes during installation. And you will have to install other fuses. Standard ones installed on a car have a current reserve of about 25% - this is the normal value used in calculating electrical circuits.

    As the load increases, the maximum permissible current becomes higher, so you need to replace several fuses, maintaining a margin of about 25%.

    Responsibility for unregistered TSU

    VAZ 2107 1982+: Appendix 1. tightening torques of threaded connections* VAZ 2107 Lada

    Car owners operating vehicles with an installed unregistered trailer hitch are subject to an administrative fine of 500 rubles. (Part 1 of Article 12.5 of the Administrative Code). It was already mentioned above that it is not necessary to take documents with you to the towbar. This is true. Fines are imposed in the following cases:

    • The product does not correspond to established standards, it is homemade, there is no information that the tow bar is registered;
    • The device is installed incorrectly or on a vehicle on which its installation is prohibited (category B);
    • The product blocks the driver's view or the vehicle license plate.

    Sometimes drivers manage to avoid administrative punishment and get off with only a warning.

    How to avoid a fine?

    According to Art. 12.5 of the Code of Administrative Offenses of the Russian Federation, punishment in the form of a warning is appropriate if:

    • The driver undertakes to register or remove the tow bar from the vehicle as soon as possible;
    • A removable model is installed on the body, which can be easily removed if necessary;
    • The device is installed at the factory or the body has factory fasteners for installing the hook.

    It is also impossible to impose a fine in cases where the towbar has already been registered and has passed the necessary examinations.

    A towbar or towbar (hereinafter) is one of the most common additional equipment on a car. It is what is used for transporting all kinds of trailers, transporting bicycles... However, while we are not using it, to put it in the language of a commoner, it just sticks out at the back. And here, recently, our valiant inspectorate, which monitors road safety, began to have questions for the owners of cars that are equipped with towbars. This is not the first time on the Internet that you can find reviews that an inspector has issued a fine for a tow bar. But how do things really stand with the fact of an installed tow bar that is not registered as additional equipment? Can they really get a fine for this? Is this legal? This is what we want to tell the reader about.

    The current state of affairs on the road

    Despite the fact that we nevertheless came to the conclusion that a fine for a tow bar is not only possible, but also quite legal, everything is not so bad. Indeed, in practice, motorists are not often issued such a fine. Let's say more, no one really pays attention to the presence of a towbar, and does not think about what the motorist is violating. Therefore, actual objectivity is not so gloomy, and until some high-profile incident occurs in our country or the idea of ​​a “fix” arises, there is no need to be particularly afraid of a fine for a tow bar. The likelihood of such administrative punishment is not high.

    Towbar for VAZ 2107 - what is it

    Installing air on a VAZ 2114: features and advantages

    A towbar or tow hitch is an additional vehicle equipment designed for coupling and towing a trailer. On the VAZ 2107, such a design is installed if the standard trunk is not enough. Elements are provided that allow, if necessary, only towing the car. As for the towbar, you can make it yourself or purchase a ready-made one and install it on the vehicle without the help of specialists from car service centers.

    What types of towbars are there?

    Before purchasing a towbar for a VAZ 2107, you need to find out what they are and what their differences are. Products are classified according to the type of hook and location of installation. For the car in question, the hooks are:

    1. simple design, when the hook is designed to transport loads up to 1.5 tons, fastening is carried out on two bolted connections;
    2. quick-release hook with a coupling connection, which allows you to reduce the overall length of the vehicle;
    3. end-type hook with a lifting capacity of 2–3 tons.


    Towbars are classified according to the type of hook (ball) and installation location

    How to attach the towbar

    The towbar can be attached in several ways:

    • there are none in the holes provided);
    • into the technological holes of the body elements (spars, bumper fastenings), into which bolts are inserted that secure the towbar;
    • into holes that are made specifically for mounting a towbar, with preliminary markings.


    Since the VAZ 2107 does not have holes for installing a towbar from the factory, they must be made independently in the bumper and body of the car

    Homemade towbar or factory one

    Despite the fact that today purchasing a towbar for a VAZ 2107 is not a problem, some motorists still prefer to make such a design themselves. This is due to the fact that factory products do not suit the owners according to some criteria, and in terms of finances, homemade towbars are cheaper. Therefore, one’s own ideas arise regarding the manufacture of a trailed one, especially since finding the necessary drawing today is not particularly difficult. But before you start making your own coupling structure, you need to think carefully and weigh the pros and cons.


    A homemade towbar will cost less than a factory one, but before purchasing and installing it, you need to think about whether it’s worth the risk

    What could be the dangers of installing a homemade tow bar? And there can be a lot of troubles:

    1. Passing the technical inspection will be problematic, although this issue can be resolved: the trailer can be removed for the duration of the procedure.
    2. A significant problem may be structural failure due to improper manufacturing or installation. As a result, you can damage not only your car, but also become the culprit of an accident.

    You need to understand that making a towbar with your own hands is a risk. If you purchase a certified product, you can be completely confident in the safety of this product.

    Factory towbar kit

    A factory towbar is a design from manufacturers who have received a license to manufacture it, while companies are engaged in the manufacture of towbars for different brands of cars. One of the main advantages of a factory design is that the coupling part is tested. This indicates the safety of the tow bar, unlike homemade options.

    The factory set of the towbar includes the following elements:

    • the metal part itself;
    • installation instructions usually take the form of a drawing;
    • fastening elements;
    • socket and wires for connecting it.


    The package of a certified towbar includes the part itself, fasteners, a connector with wires and an installation diagram

    What to consider before installing a tow bar on a VAZ 2107

    First of all, you need to take into account that the trailer for the VAZ 2107 from any manufacturer is a universal design. The device is attached with bolts to the rear bumper and body. Following the manufacturer's instructions, installation will not be difficult. However, before carrying out work, it is necessary to prepare the vehicle itself, or, more precisely, its individual parts for installation.

    In addition, you should take into account that with the installation of a trailed one, the load on your “seven” will increase, and specifically on the bottom of the luggage compartment. To avoid unpleasant situations in the future, it is better to reinforce the trunk floor, for example, with wide metal plates or washers during installation

    Experienced auto mechanics recommend treating the edges of the holes with mastic or primer after drilling them. This will prevent the metal from being damaged by corrosion.


    When installing the towbar, the trunk floor should be reinforced with wide washers or metal plates

    Tips and tricks

    A simple 7 pin socket wiring diagram suggests that you need to determine the wire routing. The most difficult point is the need to determine where the conductors are connected. However, it is not recommended to search at random.

    It turns out that it is better not to try to connect the trailer contacts in series with the indicator lamp. The fact is that if there are digital lighting control circuits, this method can lead to breakdowns and malfunctions.

    It is also recommended that before making the connection itself, check the electrical circuits in the trailer connector (especially in the area of ​​​​contacts and soldering). It is important that the contacts are not oxidized or rotted. The contacts are also checked for short circuits, especially in moving places.

    At the end of the checks, you need to draw up a routing diagram, distributing the wires by color. You also need to decide on the method of connecting the wires, their connection points, etc. In cases where the connections are located outside the vehicle interior, heat shrink is used to protect and seal the connections. Once the wiring connection is complete, a final check is made with a multimeter to check for possible shorts or poor connections.

    Self-installation of a towbar on a VAZ 2107

    A towbar or towbar is a product with which you can tow a trailer. It is known that domestically produced cars of the VAZ model range do not differ in trunk capacity, so installing a tow bar on a VAZ 2107 will be more convenient than ever, by the way, especially if you have a trailer

    Let's pay attention to the question of how to install a tow bar on a VAZ 2107, what these products are, and how they differ

    Why is it better to buy a factory towbar than to make it yourself?

    If you make a trailer yourself, which many people do, you may end up with the following unpleasant consequences:

    • There will be problems with passing technical inspection. But the problem is solved in the following way: during the technical inspection, the product must be removed.
    • A more significant problem is the possibility of beam breakage and body damage. This problem can arise: if the product is manufactured incorrectly;
    • if the device is not secured correctly;
    • when the tow bar breaks.

    If you decide to make your own, you will do so at your own peril and risk. By purchasing certified models, you can ultimately gain complete confidence in the product and its safety. Now let's find out what is included in the package of the factory tow bar.

    Factory tow bar kit

    A factory tow bar does not mean that the product is manufactured at the Volzhsky plant. The production of such products is carried out by special private organizations, which initially obtain a license, and only then produce trailers for various vehicles. The advantage of this type of device is the fact that the towbars are tested, so they are safe compared to homemade options.

    The certified device includes the following elements:

    1. the product itself;
    2. instructions for its installation, often presented in the form of a drawing;
    3. bolts for fastening;

    socket and cable for connecting it. Although on some versions the socket is sold separately.

    To install a towbar on a VAZ 2107 with your own hands, you will first need to make sure that you have the necessary material:

    • drill with a set of drills;
    • set of wrenches;
    • pliers;
    • primer;
    • insulating tape;
    • anti-corrosion mastic.

    Let’s find out in more detail what the installation of a towed trailer on a VAZ 2107 is.

    Installation of a trailed

    Let's start installing the towbar on the VAZ 2107, for which you will need to perform the following steps:

    • The carpet is removed from the luggage compartment.
    • Take the towbar and apply it to the bottom of the car. One person holds the product, and the second makes markings using chalk.
    • The marked holes should be drilled and then treated with a primer and anti-corrosion coating.
    • Now you can install the tow bar and screw it in using the supplied bolts and nuts. The bolts should be tightened in pairs until they stop. After installation, check whether the structure does not interfere with the functioning of the main components of the car: the brake system, etc.
    • Now you need to connect the towbar socket, which causes difficulties for most motorists.
    • The wiring should be packaged in heat shrink tubing.
    • Remove the trunk trim.
    • Insert the wiring harness into the hole at the bottom of the trunk through which the license plate light wire passes.
    • Connect the wires to the rear lights. If there are lugs, it is better to make a connection using them, which will allow you to quickly and easily dismantle the trailer if necessary.

    The tourniquet is fixed with electrical tape. The mounting points should be treated with mastic, which will protect the body from the negative effects of corrosion.

    Attachment points to the bottom of the trunk

    Finally, a diagram is made for connecting the wires to the rear light, based on which you will need to adjust the wires in the tow fork. Once the trailer is installed on your car, we recommend that you learn how to drive a trailer with this device. Remember that dual axle trailers require the appropriate category

    But often biaxial trailers are used for more serious vehicles, for example, UAZ, but in any case, this point is important to consider

    We recommend reading: about the rear stabilizer, installing an on-board computer, about heated seats.

    It is also important to know 5 nuances about connection:

    Look at the picture of the towbar connector. Switching off will not be particularly difficult, especially if there is a universal component element, which is a towbar connector. It is very convenient to make the connection if the plug and socket match the connectors. Accordingly, a seven-pin socket must be connected to a seven-pin plug. In this option, you can make a normal connection, do not forget to combine the required sockets with the corresponding sockets.

    Connecting the towbar socket to the car

    Before connecting the towbar socket to the car, you need to make sure that its body, cover and plug are sealed. To do this, pour water over this part and see if there are any leaks. If the structure is not airtight, then the weak points will need to be treated with silicone after the final stage of installing the tow bar.

    The outlet itself is connected in two ways:

    • Standard. In this case, no changes are expected to the vehicle's electrical system. If the trailer and trailer hitch have the appropriate connectors, then a circuit for such a connection is not required - you just need to insert the socket into the socket.
    • Universal. In the case when we are not talking about standard equipment, but about an additionally purchased towbar or trailer, a more complex connection is most often required.

    If everything is clear with the standard version, then there are two options for connecting the tow bar to the car wiring using a universal method.

    Option 1

    This method is suitable for situations where the car does not have a modern control unit, which makes it possible to connect the wires directly to the electrical circuit. This means that the wiring coming from the connector is connected to the wires of the rear light elements.

    To do this, you first need to refer to the trailer socket connection diagram, which can be found in the accompanying documents and instructions. Next, the socket itself is connected in the area where the car’s rear light harness block is located. Most often, in this place you can find a special technological window provided by manufacturers in order to simplify the procedure for replacing damaged light bulbs.

    Healthy! In this case, you must have an extra wire for the second turn signal.

    To connect the outlet this way, you can use crimp clips or simply strip the insulation from the wires, connect them and secure them by soldering. It is also worth considering that in order to connect everything correctly, it is better to arm yourself with a wiring diagram of the machine.

    Option 2

    If you are the owner of a modern foreign car, then most likely it has complex electronic components installed that will not allow you to connect the trailer using the first method. The fact is that the installed control unit constantly monitors the optics located in the rear of the car. As soon as more current consumption begins in this area, this will be perceived by the system as an error.

    To avoid this problem, an additional element is used, which is called a matching block. This device is connected to the car’s standard electrical system, and it becomes a kind of intermediary, allowing the signal to be seamlessly transmitted to the light elements of the trailer.

    Healthy! The control unit simply will not “see” the additional element, and accordingly the driver will not receive any error messages.

    If you do not want to buy a matching unit, then you can use a little trick - use a relay. By and large, it will serve as a control element that supplies voltage to the side lights of the trailer. The relay can also be installed for brake lights and fog lights (if installed).

    We recommend: Boosting the engine - the basics of boosting an internal combustion engine

    Once you have connected the trailer and checked that all systems are working properly and the lights are on, be sure to protect the internal components from moisture. Silicone is used for “gaps”, and to protect the contacts from oxidation it is recommended to treat them with graphite lubricant.

    Features of the socket connection

    To connect the towbar to the vehicle's electrical wiring, we recommend using stranded copper wire. The ideal option is a wire in which each core has a cross-section of at least 1.5 square meters. mm. The wire must have a double layer of insulation.

    After connecting the trailer according to our diagram and checking the functionality of its lighting equipment, it is advisable to take care of protecting the internal elements of the outlet from moisture. It would be a good idea to use graphite lubricant, which will also prevent oxidation of the contacts.

    How to Install a Towbar on a VAZ 2107 Video

    Zipper VAZ 2107

    A tow truck is a functional element of a vehicle designed to tow trailers of all types. In addition, this element is part of an improvement to the vehicle, which allows it to carry 1.5 or even 2 times its own carrying capacity.

    In a VAZ 2107 car this is about 350 kg. Trailers can range from 400 kg to large. 600 kg

    There are various designer tow hooks on the market, but the geometry is still there. You can find units with a meshed member welded together to the main axle. pipe. And you can also find welded structures. The back (apple) is welded perpendicular to the center shaft, which has greater strength than the previous version.

    Equipment

    When purchasing an attribute, the kit includes:

    • the tow hook itself;
    • Installation Instructions
    • mounting bolts;
    • wiring and socket for trailer connection.

    What to remember?

    Any coupling device on VAZ cars, up to 2107

    , has the same design and is therefore attached to the same number of bolts, the number of which is lower than 6-4, and 2 on the bumper mounts. Installing a tow hook on a domestic VAZ 2107 car does not require special knowledge and skills.

    Zipper VAZ 2107

    All you need to do is be persistent and careful.

    • First, the bottom of the rack must be reinforced because when the trailer and vehicle are fully loaded, the pressure on the bottom will double and the load will be concentrated in 4 points. And it can bend metal, so it is recommended to place wide plates under the rack bolts.
    • Secondly, after drilling the holes, it is necessary to treat these places with soil and mastic. This will protect not only the reliability of the fastening, but also the car itself from winter salts and moisture.

    installation

    To install the towing 2107, you will need: a drill with a drill, a pair of keys and the help of a friend. In the end, you can still mark the holes, but it will be difficult to fix the bolts.

    After all, VAZ does not provide safety pins to protect this vehicle attribute.

    So, having firmly secured the tug, proceed to the wiring. After all, the trailer has the same signal lights as the car itself: stops, turns, dimensions, reverse gears. Its technical condition has the same requirements as the machine itself. Therefore, you must take responsibility for connecting the headlights. There are several sockets for this:

    1. in a plastic case;
    2. in metal.

    Both versions are equipped with protective covers that protect the contacts when the trailer is switched off. A metal case is more reliable and durable, but such a connector will be much more expensive and is often not supplied.

    What do you need to remember?

    Any towbar for VAZ cars, up to 2107, has the same structure and, therefore, is attached to the same number of bolts, of which there are 6 - 4 to the bottom and 2 to the bumper mounts. To install a tow bar on a domestic VAZ 2107 car, you do not need a lot of knowledge and skills.


    Towbar for VAZ 2107

    Here you just need to show some diligence and attentiveness.

    • Firstly, the bottom of the trunk needs to be strengthened, because when the trailer and the car itself are fully loaded, the pressure on the bottom will double, and the load will be concentrated in 4 points. This can bend the metal, so it is recommended to place wide plates under the bolts on the luggage compartment side.
    • Secondly, after drilling holes, it is necessary to treat these places with primer and mastic. This will preserve not only the reliability of the fastening, but also the car itself from winter salts and moisture.

    Types of connection diagrams

    There should not be any difficulties in connecting a Kurgan trailer or the same MZSA with a VAZ 2110. Everything is our own, original, and therefore simple, provided by the manufacturer.

    But situations are different. Some require a special adapter adapter, others need to adjust the wiring itself and determine which wiring goes where. Supposedly incompatible trailer hitches and machines can in fact be connected. But this is quite difficult to do.

    There are several important points to consider:

    • If the machine is used to connect to different caravans from different manufacturers, it would be logical to install a pair of 7-pin sockets;
    • For Russia it is not very convenient and easy to select a “company” for 13-pin sockets;
    • Depending on the model, series and year of manufacture of the car, they may have differences in terms of pinout. It happens that side lights are output to pin 5, although on another version they go to pin 7;
    • Previous owners of used cars could well have done something weird and used their own special circuit to connect the trailer;
    • You should always check the car's electrical circuit and consult official documents.

    Not everyone has preserved their native documents. And then people turn to various forums for help, looking for answers on the World Wide Web.

    For trailers connected to vehicle towbars, I have special recommendations.

    Contact the manufacturer. Or go to a good, trusted electrician. Moreover, it is not necessary to go to the office of the company that produces the car or trailer. Everything can be found on official resources. Such information is completely true, and therefore you will not find errors common in the recommendations of supposedly skilled people.

    At first I thought that I would describe to you in detail where each contact is on the socket, where it goes and what it is intended for.

    But now they understand that the idea is pointless. It will only confuse you even more and drive you into a dead end. We need to do it much simpler. Visual examples are the best option. I will prepare for you several images showing the essence of typical pinouts on sockets of towing coupling devices. They should not act as the basis for your own connection. Remember, only official documents and manufacturer's instructions. Each machine may have its own characteristics.

    Well, let's start with the good old domestic cars. This is where we most often see trailers.

    In the case of domestically produced machines, the standard pinout looks something like this.

    Nothing complicated. But the situation with European cars. The differences are minor, but they are there. Therefore, consider what kind of car you have at your disposal.

    There is already a 13-pin monster here. In fact, there is nothing particularly difficult in connecting, but still the difference of 6 contacts makes itself felt.

    As you can see, each standard scheme has its own characteristics. Connecting a trailer to a car is more than just connecting two plugs. Sometimes you have to rack your brains here. And in order not to break it, you can turn to good specialists. For example, to us.

    Top 5 best manufacturers of farcs for cars such as VAZ 2110, Toyota Hilux

    Very often, motorists have to transport large loads. Placing them on the roof of a car like a VAZ 2110 is inconvenient and unsafe. That is why you have to deal with connecting the trailer. This must be done correctly - through the tow bar. But in order to make a reliable connection, you will need to buy a device from good manufacturers who have long proven themselves on the market on the positive side. Poor quality equipment will lead to serious consequences - if the turn signals on the trailer turn off, a traffic accident may occur.

    List of the best manufacturers:

    1. Bosal. The manufacturer provides its customers with a wide range of products. All components are qualitatively connected. The best components are used. Instructions for use are always provided with the device. It is clear and visual.
    2. Thule. The company is also known under the Brink brand. The models are quick-release, so you don’t have to spend a long time fiddling around with connecting and disassembling. The quality of materials and workmanship is very good. The brand has reliably proven itself.
    3. Auto-Hack. This model has reasonable prices, but the quality of construction is one of the best. You can find a wide selection of products in stores. Quick release models are also available.
    4. Baltex. People with domestic as well as Chinese cars can purchase. The workmanship is good, but somewhat inferior to previous models. The fasteners are made of stainless steel, and therefore you can drive with a trailer in the rain without any problems.
    5. Avto S. Suitable for Chinese and Russian cars, both Toyota Hilux and Lada Vesta. The prices are very low.

    To transport a large load, you need to attach a trailer to your vehicle. This can be done through the trailer hitch and a tight connection to its socket. The trailer's electrical wiring (cable) leading to its headlights, when connected to the main vehicle's wiring, will alert rear road users to various actions by the driver. To correctly connect the signals, trailer connection diagrams and towbar socket pinouts must first be prepared.

    Logically, what is a tow bar...

    In essence, in order to arrive at a fine pattern, it is necessary to relate actions or inactions to some condition or fact, and also to prove its violation. Well, if you know that under Article 12.5 of the Code of Administrative Offenses of the Russian Federation it is quite possible to issue a fine. And this article of the Code of Administrative Offenses of the Russian Federation prescribes a fine for something not working or re-equipping a car, it turns out that the towbar itself needs to be connected to additional equipment - that is, to change the design of the vehicle. Here, the first thing you need to do is refer to the Technical Regulations of the Customs Union. After all, it is there that you can find a definition of what a design change is.

    In fact, if we develop this idea, then I would like to know whether the towbar will affect the very same road safety or not. Here it is necessary to turn to the definition of road safety. To do this, we quote the Federal Law of December 10, 1995 N 196-FZ “On Road Safety”

    Now we draw a conclusion. If a towbar can influence the provocation of an accident or its consequences, then in essence this is a design change. It is possible to logically conclude that a tow bar can influence the role of probability in an accident, but it would be absurd. But the conclusions about the consequences of the influence of a tow bar in an accident are clear. The towbar protrudes beyond the rear bumper, which means it may well affect the consequences of an accident. Since first of all the impact will be on the tow bar, and only then on the bumper. As a result, a towbar can be considered a change in the design of the car, which means Article 12.5 of the Code of Administrative Offenses of the Russian Federation, or rather a fine according to it, is quite likely for motorists with a towbar.

    However, there are exceptions here that will benefit the car enthusiast.

    Our lawyers will advise you on any issues out of turn. Question Answer This is the exclusion of components and equipment not provided for by the design of the vehicle, carried out after the vehicle was produced and affecting road safety.

    Yes, it is required if this device is not provided for in the technical documentation of the transport.

    When installing components on a vehicle: - intended for this vehicle and having passed the conformity assessment as part of this vehicle, which is confirmed by the documentation of the component manufacturer; — provided by the vehicle manufacturer in the operational documentation. Look in the instruction manual.

    Matching block

    If we are talking about a modern car with complex electronic components, the first option for connecting a trailer will not be the best choice. The control unit tests the rear optics. When it determines that it is consuming more current, it will display an error message. In such cases, the so-called “matching block” is used. It is also used in the case of transmitting control signals via a multiplex bus.

    The wiring is connected to signal circuits, only in this case the signals to the lighting equipment of the towed device come not from the car, but from the matching unit, and its presence is not perceived by the electronics. Additionally, the unit must be connected to a used car.

    Connecting a caravan requires attention to more than just how well the trailer's outlet circuit matches the electrical outlet on the vehicle. When we try to connect a towbar to a vehicle like a VAZ 2107, we will not have any difficulties - the wiring is installed directly. Drivers of modern cars know that the reaction of the on-board computer to a trailer can be negative and lead to problems.

    Universal connection method


    For owners of modern cars, connecting the socket will be easier.
    And all this is due to the fact that the wiring itself is much more complex. You will have to install a special matching unit. With its help, all optics of the tow hitch are diagnosed. And if the current consumption increases (during a short circuit), the driver will be warned. A notification will also occur if one of the lamps fails (the current consumption decreases). For this reason, experienced auto electricians advise using a matching device. Installing a towbar socket on VAZ cars using a universal method:

    1. Install the matching device and connect it to the car wiring. Connect the connectors according to the diagram. To activate the matching device, you need to turn it on by applying power. The optics on the trailer will start working, depending on what signal is being received.
    2. In rare cases, the connectors on the matching unit and the trailer do not match. There are many manufacturers of electrics and trailers, which is why such “disagreements” happen. But if you have a pinout diagram for the trailer plug and the car’s electrics, you can solve this problem quite quickly.

    The functioning of optics on a trailer depends on the quality of installation. Carefully insulate exposed wire sections to prevent short circuits.

    Where to get documents for TSU

    You will have to obtain the necessary documents from several authorities:

    • Quality certificates are provided complete with towbars if the car owner buys a product manufactured at the factory;
    • Homemade towbars must be additionally checked for compliance with the car brand and characteristics; a conclusion can be obtained from the service center or from traffic police officers;
    • A diagnostic card is also issued at service centers;
    • Application forms are issued to the traffic police;
    • The driver must have technical passports for the car and trailer;
    • The contract for the purchase of the trailer hitch and fastening element can be replaced with a receipt and a warranty check.

    It is recommended to call the nearest branch in advance, request information on the necessary documents and addresses where they can be obtained. In some departments, the examination and examination procedures differ.

    Installing a towbar on a VAZ 2107

    To install the tow bar on the “seven” you will need the following tools and materials:

    • drill with a set of drills;
    • set of wrenches;
    • pliers;
    • primer;
    • insulating tape;
    • anti-corrosion mastic.


    Before installing the towbar, prepare the necessary tools and materials

    How to install a tow bar

    The process of installing a tow hitch on a VAZ 2107 is carried out in the following sequence:

    1. Remove the carpet from the trunk.
    2. Take the towbar and apply it to the bottom of the car for marking. An assistant holds the structure, and a second person marks the installation site with chalk.
    3. After marking, holes are drilled in the bottom and bumper of the car in accordance with the diameter of the bolts and the design of the trailer itself.
    4. After drilling, the holes are treated with primer and covered with anti-corrosion material.
    5. Install and secure the tow bar. The fasteners are tightened until they stop.
    6. Connect the trailer socket.

    A little about self-production

    I am categorically against assembling towbars and trailers with my own hands, since they extremely rarely meet the quality and safety requirements for such structures.

    But I still think it’s correct to give an approximate manufacturing diagram. To get started, you will need all the consumables, tools and a welding machine. Each machine has its own coordination scheme, design features and other points. Therefore, even with a great desire, I cannot offer general assembly instructions for everyone.

    Materials you will need:

    • a ball mechanism that has built-in eyes (you will have to buy it on the market, otherwise there is no other way);
    • a pipe made of durable iron about 1 meter in size;
    • corner beam 0.5 meters;
    • 2 nuts for tow bar;
    • bolts with a diameter of 14 mm and corresponding washers for them.

    In order to assemble a full-fledged trailer hitch from all this (preferably removable, since monolithic structures are not a priority now), you will have to put in maximum effort and caution.

    Installing a towbar — Lada 2107, 1.6 l., 2002 on DRIVE2

    Hello

    , I already wrote that the car was primarily bought for household chores, and anyway to drive through forests and fields, and first of all it was necessary to install a tow bar, but either there was no money, or I was too lazy to buy and install it, in the end I decided I still bought it, but I couldn’t find it anywhere, I had to order it at the store. I picked it up two weeks later, I didn’t have it lying around for long, and I don’t like buying something for the car and leaving it to lie around later. In principle, the towbar is not especially needed, but still, from time to time I need to bring something, I hooked up the trailer and drove off. My father used to have a little one with a towbar, then he sold it, and in the end there is a trailer and it’s standing idle) so 7k had to take the rap. Here's the tow bar


    The installation turned out to be much simpler than I thought, the towbar is attached to the towing hooks in the front, four holes are made in the back under the car and fastened, I drilled, primed, painted and coated it with mavilya, I put all the bolts on lithol, as if not how, it will not protect the body much. socket, I didn’t drill anything for the wires, I went the other way; there is a tab for the trunk ventilation, I bent it a little and pushed the wires through.


    I also didn’t bother about how to connect the wires, before inserting the wires, I secured the wires into the sockets by poking them, then I just went to the trailer, connected the socket to the trailer, and threw a minus from the battery onto the trailer, and took turns trying what would light up where and on the piece of paper I signed what color the wires are responsible for, two wires are extra, my trailer doesn’t have a reversing light or fog lights. Then I calmly connected it to the lights, it was a pity to cut the wiring on the car, I decided to just pull the contacts out of the connector and solder them to them


    Yes, on the car I turned on the lights, brake lights, and turn signals one by one and looked for the required wire with a tester. And that’s all, there was nothing critical, I was glad that the towbar included a cover for it. The trailer itself, at one time it was also put in order, and processed and painted, is in the garage, we drove along the highway with it, it is my age)))

    Good luck to everyone on the roads, that's all)

    Towbar connected to frame

    Thus, to make the device, you need to find a ball with eyes (on the market or used does not matter). After that, remove the bumper, cut off the lugs and make a hole using a drill and a drill bit. Next, you will need a pipe of suitable diameter up to 1 meter long. Connect with a fastening weld. After this, in the middle of the pipe, another pipe is strengthened at a right angle by welding. After this operation, the structure can be primed and painted. To increase the spar, you can insert a small piece of angle iron with a nut welded to it, eventually you will get something like a removable towbar.

    Mounting to body

    We made a towbar with our own hands and now we need to attach it to the car body.

    1. The first thing to do is to combine the trailer frame with the body frame frame. This allows you to get a load-bearing body. To get the platform, you will need to use five small crossbars and place them between the crossbars.
    2. Then, it is necessary to weld the longitudinal elements on both sides. It is necessary to install 4 racks through each crossbar and weld them carefully. Now you will need rectangular pipes.
    3. I recommend making the sides folding, as this will allow you to transport long and large objects. Lay a sheet of iron on the floor. A sheet of iron needs to be welded to the grille of your body.
    4. If suddenly you do not have the material for your homemade trailer hitch, then the supplier of the tools you will use will be an old car. You will need two springs from it; they will connect the beams and the frame. Now your trailer will need wheels, these can also be borrowed from an old car.

    To install the tow hitch you will need an inspection hole or a lift. Before installing, I recommend disconnecting the car from the battery. Then remove all contents of the trunk and remove the trim.

    Attention to details

    After this, as they say, you need to estimate the towbar at the attachment point. Next, you must first attach the structure in a place prepared for this with the help of bars, clamps, or something else; help from a friend will not be superfluous.

    The second stage is drilling holes for fastening. For this job you will need a drill. Holes are made on both sides using a drill and a drill bit with a diameter of 12.5 mm. Insert washers and bolts into the formed holes and tighten the nuts. Tightening is done using a wrench of the appropriate diameter.

    Then you need to make two holes on the inside of the trunk and in the lower part of the spar, using a reinforcing lining. Bolts are inserted into the drilled holes, linings are put on, followed by washers, and then tightened with a wrench to “17-19”.

    At the final stage

    Make a hole in the bottom of the trunk to connect the wires to the trailer outlet. Before you start drilling, think carefully and make a mark of the place that needs to be drilled. Secure the connector to the towbar, and then through the hole in the bottom of the trunk, pull out the wire and connect it to the socket, taking into account the color of the wires.

    WHERE AND HOW TO INSTALL THE SOCKET

    The socket is usually installed on a special bracket provided on the towbar from the factory. All that remains is to secure the round connector and make the connection.


    The socket is mounted on a special towbar bracket

    HOW TO CONNECT WIRES TO AN OUTLET

    The towbar connector on the seventh model Zhiguli is connected in the following order:

    • The wiring that comes with the tow hitch is placed in a corrugated tube.
    • Remove the luggage compartment trim.


    To connect the socket from the standard wiring, you will need to remove the trunk trim

    To lay the harness, make a hole in the trunk floor or use the bumper bracket.


    The harness with wires is laid in the prepared hole or in the bumper bracket

    Connect the wiring to the rear lights.


    The wires from the connector are connected to the car’s standard wiring, going to the rear lights.

    The harness is secured with electrical tape or plastic ties.


    The tourniquet is fixed using electrical tape or plastic ties

    All fastening areas and elements are treated with anti-corrosion materials so that in the future the device can be easily dismantled and the spread of rust can be prevented.

    Important information

    You can connect electronics in a simpler way. To perform such an operation, it is necessary to combine several leashes into a group and create an effective symbiosis of the supply of electrical signals. You can splice the contacts of two headlights, reverse lights, brake lights, fog lights and side lights. This is explained by the fact that when operating the car they will be used synchronously. Fastening is provided using brackets.

    The next method involves changing the car's electrical system. This change consists of combining several wires that lead to the rear light and signal electrics of the trailer. They must be connected to the wires from the coupling device. If the vehicle has a complex electrical circuit, then you will have to spend a little more effort than in previous options.

    If the car's signal and light bulbs work without a special microprocessor, then you can connect a 7-channel towbar connector. Before you begin the operation, you should make sure that there are enough wires. If necessary, you can make the wiring elements yourself using a three-core copper wire of one and a half millimeters. They should be marked “PVS”.

    If the connection is made directly, you must have a diagram of the towbar in front of your eyes, as well as a diagram of the car socket.

    Towbar socket

    To make the connection correctly, you need to supply turn signals, brake lights, as well as side and fog lights via one wire; you also connect license plate lighting there. You will also need to connect several wires that go to ground, the reversing light, if there is one.

    A special adapter is also installed on the electronic units. We are talking about a coordination unit between the electrics, the towbar and the towed part of the car. If there is such a connection, all connected parts will work smoothly and will not create problems for the motorist. Connecting the towbar coordination unit is done by yourself.

    Photos of towbar connection diagrams will always help in your work if difficulties arise.

    The definition of a connector can be described as a combination of plugs and sockets that are connected after the trailer is attached to the hitch.

    Here it is important to pay attention to who is the manufacturer of the towing device and the trailer itself. In some cases, the number of contacts they have is different. Our standard pinout includes 7 contacts. This is a European and domestic manufacturing principle. But if you have an American car in front of you, be so kind as to understand the 13-pin connector. It is also important that the contacts on plugs and sockets are counted differently.

    If you need to connect different types of trailers and vehicles, you will need to use a special connection block or adapter. Alternatively, you can make adjustments to the pinout. But this will require deeper knowledge of auto electrics, as well as a detailed study of the design of the car itself.

    Figure 4. 5 nuances about connecting the towbar socket. Look at the towbar connector in the picture. Switching off will not be particularly difficult, especially if there is a universal component element, which is a towbar connector. It is very convenient to make the connection if the plug and socket match the connectors.

    Connecting a trailer socket

    Step-by-step description of the work

    ✓ First you need to remove the bumper. ✓ Next – cut off the eyes. ✓ Here you need to take a drill and make holes.

    ✓ We take a welding machine and weld the fasteners. ✓ Now you need to weld the second tube in the center to make a right angle connection. ✓ You need to take a grinding wheel and coarse sandpaper and clean the seam and edges of the tubes. ✓ The manufactured structure is coated with a primer. ✓ Now the structure is covered with paint.

    To strengthen the spar, we install a small angle with nuts. This will create a tow bar with a removable structure. You can use headlights to power the towbar, and use a connector to power the socket. Ready! Now you have a full-fledged homemade tow bar.

    When making a homemade towbar, you need to try it on all the time, controlling where it is placed on the car.

    Expert recommendations

    Many car owners, not wanting to overpay for cargo transportation services, decide to make a towbar with their own hands. It may be needed in many cases. In the modern world, living without a trailer and having a car is quite difficult. Everyone sooner or later makes repairs in their homes, and to transport building materials you have to overpay and order delivery. Those who own a country house or dacha, at the end of each season, rack their brains: how to transport the harvest to their city home. Residents living near the seas transport their boats to the water at the beginning of the season. In general, a towbar is an irreplaceable thing that should be on every car, unless in your garage, in addition to a passenger car, there is also a truck.
