towbar question

[Transporter]

Thanks Maverick for detailed description of the complexity of connecting the tow bar and its wiring to the car's electrics and electronic components.

It should be more than enough warning to everyone thinking of retrofitting trailer controller with something else.

DON’T DO IT and use correct part from VW or the warranty is void, if you muck something up in the electrics on the car, it could cost much more later.
