Towbar for VAZ 2107

A towbar is an additional coupling device designed for towing a trailer. Installing a towbar on a VAZ 2107 allows you to compensate for the relatively small volume of the trunk and the carrying capacity of the “seven” by transporting cargo in a trailer. In the factory configuration of the VAZ 2107, only towing eyes are provided, to which you can hook a cable to tow the vehicle. But you can make your own or purchase a towbar for a VAZ 2107 in a store and install it on the car.

TOWER FOR VAZ 2107 - WHAT IS IT

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 ARE THERE ARE TOWER COPS?

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:

simple design, when the hook is designed to transport loads up to 1.5 tons, fastening is carried out on two bolted connections;
quick-release hook with a coupling connection, which allows you to reduce the overall length of the vehicle;
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 IS THE TOWCH ATTACHED?

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 TOWCH OR FACTORY HANDLE

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:

Passing the technical inspection will be problematic, although this issue can be resolved: the trailer can be removed for the duration of the procedure.
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.

EQUIPMENT OF A FACTORY TOWLER

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 SHOULD BE CONSIDERED BEFORE INSTALLING THE TOWER COVER 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 the installation process. 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

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.

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

Hello, I already wrote that the car was primarily purchased for household chores, and anyway to drive through forests and fields, and first of all it was necessary to install a towbar, but either I don’t have the money, or I’m too lazy to buy and install it, in the end I I decided to buy it anyway, but I couldn’t find it anywhere, so 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 to buy something for the car and leave it lying around later. In principle, the tow bar is not particularly needed, but still, from time to time I need to bring something, I took it and hitched the trailer and went. 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 at the front, four holes are made in the back under the car and fastened, I drilled, primed, painted and coated it with mavilya, put all the bolts on lithol, and it won’t protect the body much.

I didn’t drill anything under the socket, under 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)

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.

The tow bar is designed for towing various types of trailers and other vehicles.
Due to the fact that the load on it will be very large, the reliability of the fastening must be high. In addition, each towbar is equipped with wiring for connecting signal lights. A towbar is a functional element of a car designed for towing various types of trailers. In addition, this element is some part of the improvement of the car, which allows it to transport 1.5 or even 2 times more than its own carrying capacity.

For a VAZ 2107 car it is about 350 kg. Trailers can be from small 400 kg to large – 600 kg.

VAZ 2107
There are different tow bars available for sale in terms of design, but the geometry is the same for all. You can find devices with a towing element welded together with the main axis - a pipe. You can also find welded structures. The trailer part (apple) is welded perpendicularly to the central bar, which has greater strength than the previous version.

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.

How to avoid falling asleep while driving at night: 15 useful tips

Category: Instructions

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. Electrics are a very important component of a car. Any mistake made when connecting incorrectly can even result in a short circuit and damage all electrical equipment.

I very much doubt that anyone wants to face this. Follow this simple advice.

Pinout options

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.

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.

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:

in a plastic case;
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.

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.

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:

the product itself;
instructions for its installation, often presented in the form of a drawing;
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.

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 two-axle trailers are used for more serious vehicles, for example, UAZ, but in any case, this point is important to take into account.

Do-it-yourself trailer hitch

You can make your own towbar for a passenger car using an angle grinder and a welding machine. We present the basic algorithm for the manufacturing process:

remove the rear bumper;
find the holes that lead into the voids of the side members;
measure the length of the segment between the holes found;
cut a section of steel pipe 50x50 mm according to the obtained length;
make a mark in the middle of the workpiece;
take two pieces of 5 mm thick sheet steel measuring 20x7 cm and make holes 5 cm in size at the edge of each;
place the strips on the pipe with the holes and weld them - the distance should allow you to place a coupling hook with a ball between them;
secure the hook with nuts and bolts 10;
then we move on to working on the attachment to the side members - weld steel strips 5 mm thick and 30x7 cm in size onto the ends. The direction should be opposite to the hook, and with the hook bracket the angle should be 900;
insert these strips into the side members;

How to make a homemade towbar for your car

drill holes with a diameter of 12 mm in the rear side members and inserted plates;
weld nuts of the same size to them;
take a 3 mm thick plate and mark the holes for the socket, then drill them;
weld the plate to the hook bracket, install the socket on it.

The product is ready - you can install it and connect it to the machine’s electrical network.

How to avoid mistakes when connecting pinouts to 7 pins

To avoid making mistakes, follow the diagrams.

Below is a picture for pin 7. The coloring is standard and is used on Russian-assembled cars, for example, on the VAZ 2107. But sometimes there are some color deviations. If you are using a European car, like a Renault Duster, then not all connectors may be used.

Figure 2. Color scheme

Explanation of colors:

Left turn signal control.
PTF. On foreign cars this contact is usually not used.
Weight.
Control of right turn signals.
Left side lights.
Stop lights.
Right side lights.

The seven-pin connector is most often not used on modern foreign cars. 13 pins are connected there. But if an old type of plug is installed on the trailer, it must be connected to the new Euro connector using a conductor. This is much easier than replacing the entire connector on the car.
