Tow bar wiring

Tow bar electrics are mandatory when using a bike carrier, trailer or caravan. This is a requirement stated by the law. A tow bar electric kit ensures that the electricity for the lighting of your trailer or bike rack functions properly. There are two different types of electric fittings, namely the 7-pin and the 13-pin plug. The 7-pin cable is often used for small trailers and bike carriers. A 13-pin cable is often used for caravans and large tandem axle trailers. At Winparts you can easily fill in your number plate and the suitable tow bar electrics applicable to your car will be displayed. You can choose from a number of top brands such as BrinkECS Electronics and GDW.

Do you want to get out and about and taking your bike carrier, trailer or caravan with you at the back of your car? In such a case you are obliged by law to ensure that all electricity such as the lighting works properly. To ensure that the electrical circuits are in order, you need tow bar electrics. It is important that the bike rack or trailer lights, such as the braking lights, work at the right time. Tow bar electrics are connected directly to the cars electrical circuit.

Universal or car specific tow bar electrics

At Winparts we have a wide range tow bar electrics; universal and car specific. Universal tow bar wiring fit on almost all vehicles. However, a disadvantage of universal cables is that they are not suitable for Park Distance Control (PDC) and on-board computers. Car specific tow bar electrics are, as the name implies, specific for a brand, model and type of car. This ensures that all functions work properly. All you have to do is enter your number plate on our website and the appropriate tow bar electric kits are displayed. It´s up to you to choose between a 7-pin or a 13-pin plug connection cable. The difference between 7-pin and 13-pin will be explained below.

7-pin or 13-pin tow bar wiring

There are two types of wiring; the 7-pin and the 13-pin tow bar wiring. A 7-pin cable set transmits all the electrical functions of the car such as indicating lights and brake lights. The 7-pin tow bar wiring is very suitable for bike carriers and trailers. 7-Pin cables have the disadvantage, however, that they do not support reversing lights and constant current. This makes them less suitable for larger trailers and caravans.

A 13-pin tow bar wiring cable is required for the use of caravans. These support the constant power supply of the caravan, which is required for a refrigerator and interior lighting. The 13-pin plug cable sets comply with current standards and have a number of advantages such as safe locking system, water splash-proof connection and supporting reversing lights.

Is your car equipped with a 13-pin plug, but your bike carrier or trailer has a 7-pin plug? No need to worry. With an adapter plug, you can easily convert the connection.
