Towbar 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 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 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

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.

Types of towbars for VAZ 2107

Before purchasing a towbar for a VAZ 2107, you should familiarize yourself with their design differences. They can be roughly divided according to the type of hook and attachment points.

Hooks come in the following types:

• A simple hook with a lifting capacity of up to 1.5 tons, secured with two bolts.
• Quick-release hook with a coupling connection, allowing you to reduce the length of the vehicle.
• End hook with a lifting capacity of 2-3 tons.

Places (types) of fastening towbars are as follows:

• In the holes provided by the manufacturer for attaching the towbar (there are none on the VAZ 2107).
• Into the technological holes in the body into which the towbar mounting bolts are inserted. These are holes in the side members, bumper mounts. Sometimes during the fastening process you have to drill them out or add a few extra ones.
• In holes that are drilled specifically for attaching a tow bar. The latter is used as a template for marking.

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;
4. 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.

What you need to connect the tow bar

To connect, you need spare parts that are sold in any specialized store:

• Socket housing. It must have a lid and a rubber seal. All components must fit tightly together. If play is detected, it is better to select another part. The contacts should not dangle in the sockets. It is imperative to check the condition of all threads on this component.
• Single-core wire used in car wiring. Its cross-section should not be less than one and a half square meters. ml.
• Terminal blocks. It would be better if they had safety sockets.
• Corrugated hose. It can be either metal or plastic. Electrical wiring runs through it.

To secure the wires you will have to buy several plastic clamps. You will also need a silicone gasket.

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.

Installing a towbar on a VAZ 2107

Before installing the tow bar, you should check the condition of the paint on its surface and, if necessary, treat it with a primer and anti-corrosion coating. This part is especially susceptible to moisture and other chemically active substances, so additional protection against corrosion will not hurt. Next you should do the following:

• Remove the trunk mat.
• Attach the towbar to the bottom and mark the locations of additional mounting holes.
• Drill holes and treat their edges with a primer and anti-corrosion coating.
• Install the tow bar on the VAZ 2107 and tighten the fastening bolts.

• Thread the wiring included in the delivery kit of the towbar into the heat-shrinkable tube and shrink it so that it tightens and protects the wires (instead of the tube, you can use a winding of electrical tape).
• Remove the rear trunk trim.
• Pass the wiring harness through the hole through which the license plate light wires pass so that it goes down to the towbar from above. If the harness does not pass through, you can make an additional hole for it in the lower part of the trunk.
• Using pliers, install the fuses on the harness on the trunk side.
• Connect the wires coming from the fuses to the rear lights.
• Place the ends on the other end of the harness.
• Install the connecting plug and connect the wire lugs to it.
• Secure the harness to the towbar using electrical tape.
• Treat the places where the towbar is attached to the car body with mastic to protect the body and mounting bolts from corrosion.
• Install the rear trunk trim and lay the carpet.

Installing a towbar on a VAZ 2107 expands the capabilities of the car. By securing the trailer, you can use the “seven” as a fairly spacious and heavy-duty cargo transport. This makes it convenient to transport crops from the dacha or building materials for repairs or housing construction. Also, the presence of a towbar facilitates and improves the fastening of the tow rope. It makes it easier to pull another car out of the mud or tow it to a repair site.

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.

Responsibility for unregistered TSU

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.

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.

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:

1. Left turn signal control.
2. PTF. On foreign cars this contact is usually not used.
3. Weight.
4. Control of right turn signals.
5. Left side lights.
6. Stop lights.
7. 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.

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.

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.
