Product details

This 7 pin wiring kit for your MERCEDES-BENZ C-CLASS Sportcoupe is manufactured by TowTec for your car. The operation of this 7-pin electrical kit is very simple: It is detected by the data bus system in your MERCEDES-BENZ C-CLASS Sportcoupe and is ready for operation after the vehicle has been coded for trailer operation. From now on, the electrical kit will inform you via the car's own system if the trailer lights are faulty.

The automatic deactivation of the parking assist function is supported by this 7 pin CAN-bus module kit. High-quality, vehicle-specific plug connectors, colour coding, custom cable lengths and a detailed C-CLASS Sportcoupe C-CLASS Sportcoupe installation manual are all part of this wiring kit. This electrical kit is installed in the boot only. A continuous current connection (terminal 30) for the trailer control unit must be available in the rear of the vehicle. No drilling in the rear panel of the vehicle. A grommet is already present on your MERCEDES-BENZ C-CLASS Sportcoupe. It is used by this vehicle-specific 7 pin wiring kit. The socket of the electrical kit is already connected. It is therefore not required to connect each cable to the trailer socket.
