Product details

This 13 pin electric wiring kit from TowTec is made specifically for your MERCEDES-BENZ GL-CLASS . This 13-pin electrical kit connects to the existing data bus system in your MERCEDES-BENZ GL-CLASS . Faulty trailer lights will be indicated by the car's own system. After installation of this electrical kit, the car needs to be coded for trailer use.

An automatic deactivation of the parking assist function of your MERCEDES-BENZ GL-CLASS is supported by this 13 pin CAN-bus module electrical kit. Included in this kit: high-quality, vehicle-specific colour-coded plug connectors, custom cable lengths and a detailed MERCEDES-BENZ GL-CLASS installation manual. 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 need to drill into the rear panel of the vehicle. A grommet already exists on your MERCEDES-BENZ GL-CLASS . It is used by this vehicle-specific 13 pin electrical kit. The socket of the electrical kit is already connected. It is therefore not required to connect each cable to the trailer socket.

Extend pin 9 of the trailer socket to steady plus to power electric items in the trailer with the 107650 with steady-plus function. Or you can use pin 9 for steady plus and pin 10 to charge a second battery in the trailer. A combinet retrofit solution for steady plus and charge 139243 is available separately.
