A pendant is extremely practical and versatile. When moving, with green waste or for leisure activities, for example. So that it can be operated safely, it has, like the pulling car, rear lights that indicate braking, turning and reverse gear and ensure the necessary safety in the dark. So that these components are supplied with electricity and light up at the right time, synchronously with the rear lights of the car, they are connected to the vehicle via a cable. The "socket" into which the trailer cable is plugged is called the electrical kit. This is next to the trailer hitch and is usually covered with a protective cap to keep dirt away from the contacts. Depending on the design, there are different numbers of poles under the protective cap. For older trailers (1980 and earlier) the seven pole system is common. Modern trailers use the system, which has 13 poles. Both systems meet the legal requirements and can also be connected to each other via adapters. All common systems and modern electrical kits can be found in our Q-Parts24 online shop. Shop conveniently and inexpensively.
If you use your trailer, it makes sense to regularly check that the rear lights are working properly, especially after they have been parked for a long time. If the different lights no longer light up correctly, this can have numerous causes. In addition to a defective electrical kit, a defect in the cable, a broken lamp or a problem in the vehicle electronics are also possible. A complete failure of the trailer's rear lights or incorrect activation always indicate a problem with the spare part. If you want to replace an electrical kit, you must first disconnect the battery because you are working on the on-board electronics. Remove the bodywork and trim parts from the tow hitch and, in the case of initial installation, remove the rubber plug at the future location of the wiring harness. Disconnect the old wiring harness and remove it and the old wiring harness. Now you can insert the new wiring harness. The new socket is connected and fixed to the mounting plate. Now remove the Sam (if installed) and insert the plugs of the wiring harness into the sockets marked with the same colour. Then the Sam can be mounted again and the battery can be connected.
If an electrical kit is defective, it must be replaced before driving with a trailer in order to keep the vehicle combination roadworthy. Such a component is also indispensable if you want to retrofit a trailer hitch on your vehicle.
