Product details

This 13 pin electric wiring kit from TowTec is made specifically for your MERCEDES-BENZ GLA-CLASS . The operation of this 13-pin electrical kit is very simple: It is detected by the data bus system in your MERCEDES-BENZ GLA-CLASS 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.

An automatic deactivation of the parking assist function of your MERCEDES-BENZ GLA-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 GLA-CLASS installation manual. No drilling in the rear panel of the vehicle. A grommet is already present on your MERCEDES-BENZ GLA-CLASS. It is used by this vehicle-specific 13 pin wiring kit. It's not required to connect the cables to a trailer socket. A socket is already connected with this kit.

The trailer socket is already connected with pin 9 to the steady plus (to operate electrical loads). Extend pin 10 with accessory 139243 to charge a battery in your trailer.
