Product details

Are you looking for a specific wiring kit that is suitable for your vehicle? Then this 13 pole wiring kit from TowTec is just right for you. The handling of this 13 pole wiring kit is extremely simple: It is recognized by the data bus system in your vehicle and is ready for use after coding the vehicle for trailer operation. From now on, the wiring kit will inform you via the vehicle's own system if the lighting on the trailer is faulty.

The factory-fitted parking aid on the vehicle is automatically deactivated by this 13 pole data bus wiring kit. The user-friendly installation instructions, the high-quality, vehicle-specific plug connection and the cable lengths and colors matched to the vehicle are the most outstanding features of this wiring kit. The installation of this electrical kit takes place in the boot only. Prerequisite for continuous current (terminal 30) for the trailer control unit is available in the rear of the vehicle. Your vehicle already has a cable feed-through, which is used by this vehicle-specific 13 pole wiring kit. This eliminates the need to drill into the rear panel of the vehicle. It's not required to connect the cables to a trailer socket. A socket is already connected with this kit.

In some countries it is not allowed to use a bicycle carrier with this towbar because there is no option to automatically turn off the fog lights.

It is possible to extend pin 9 of the trailer socket to steady plus (to power electric items in the trailer) or pin 9 to steady plus and pin 10 to charge (e.g. a separate battery in the trailer). By adding the extension set 107650 you can combine charging and steady plus.
