There is an opinion among motorists, that it is not so difficult to connect the towbar, and any beginner is able to cope with this work. In principle, if we talk about attaching a trailer to a car, then here and, truth, no difficulties will arise. However, if we talk about the electrical connection of the trailer, that this may confuse many car owners. And often to complete the case requires a wiring diagram.
Here we will not consider the feasibility of having a towbar on the car, since in such cases this towing device is vital. Most often they have a special area, where the towbar socket is located. And this outlet has a special cover, which provides protection against negative factors.
Sockets are the most common, which are equipped 7 or 13 contacts. Cars, who travel on Russian roads, usually, equipped with 7-pin devices. As for the sockets, having 13 contacts, then they are more common on cars, used by people in Europe and the United States.
These sockets differ from each other in terms of the use of additional contacts. With the help of the latter, you can use the following additional devices, as fog lights and other electric stuffing of trailers, which are common in western countries.
How to connect a towbar socket
Faced with the problem of connecting the socket, the owner may consider one of two methods:
- standard;
- universal.
The first method can be considered only if, that at the towbar, as in the case of a car trailer, there are appropriate connectors, which allow you to make connections. Then the owner can do the job, even without a wiring diagram of the trailer.
After all, in this case, all actions will be reduced to the combination of the socket with the socket. Often information about the thermostats of the towbar socket can be obtained from the operating instructions of the car. This is exactly what should be done, because the owner does not have to change the electrical system of his car in any way.
However, this is often the case, that the owners have to resort to the help of a universal method. However, to get a better idea of the features, both of these options will be considered below.
the first way
The design of the car does not provide a modern electronic control unit. This allows you to connect electrical wires to existing electrical circuits, without resorting to any splitters. In other words, all work will be reduced to the connection of wires, coming from the connectors, to the rear lighting.
connection technology
First, what you need to do here - read the wiring diagram. Further, the socket needs to be connected there, where are the harness pads of one of the rear lights of the car, using the appropriate connectors.
Upon closer inspection, a technological window can be found there: manufacturers do it on purpose, so that the owner does not have problems in case of replacement of burnt out light bulbs. However, you should immediately prepare for it, that there will be an extra wire, as we will have to connect the second turn signal.
This problem can be solved as follows:
- by connecting to 3D clips;
- you can first clean the wire from the insulation, then connect it to the wire, coming from the socket, then secure the connection, using soldering.
For such cases, it is not superfluous for the owner to have a wiring diagram of the car. If you are going to do this work for the first time, it does not hurt to read the video first, so you know for sure, how to do everything right. When will you start doing this work yourself?, then you must always focus on the connection scheme of the towbar socket.
the second way
Owners of modern cars, having a rather complex electronic electronic filling, do not use the first trailer connection method. One of the functions of the control unit is to constantly check the condition of the rear optics. Have a moment, when it turns out, that the rate of current consumption is increased, the corresponding error signal will be received.
In such a situation, experts usually resort to the device, referred to as the "negotiation unit". It is also used then, when you want to configure the transmission of control signals using the multiplex bus.
- First, what needs to be done here is to connect the matching unit to the car's standard electricity. Then the unit is turned on, from which the corresponding signals will be received on the lighting equipment of the trailer. Now the car's control unit will no longer be able to recognize the device, so that the owner can easily connect the towbar.
- If you find a connector while inspecting the machine, which has a slightly different implementation, than that, which is used on the trailer, it is best not to try to solve this problem yourself, and seek the help of specialists. Of course, you can always do everything yourself, but for this you must have at hand the wiring diagram and contact temperature controllers. Quite often the owners, who have certain skills, able to solve this problem without assistance. According to the same scheme perform the connection of the cargo trailer.
important nuances
The main thing, What you need to keep in mind is that connecting the trailer's electricity is a must. Therefore, the importance of this operation should not be underestimated, thinking, that other road users will be careful while driving. If you decide to ignore this, then this may be grounds for imposing a fine on you. So every time, when you get ready to go, find a couple of minutes for that, to make sure that the trailer signal lights are working.
conclusion
If you own a car, which you use in conjunction with the trailer, then you need to take care of connecting electricity to it. If you wish, you can do this work yourself, it is enough to find a socket, whereupon, focusing on the connection scheme, it is possible to finish the case quickly and without special expenses. But if you are doing this work for the first time, then you will definitely need a socket wiring diagram.
Particular attention should be paid to this, that there are different ways to perform this operation, what you need to be informed about before, how to start solving this problem. Therefore, first of all you should theoretically prepare for the socket connection, so that you do not waste your energy and time.
