hi this my first post, can anyone please help, im fitting a towbar to my 2002 (52) 1.9 tdi and it has got the bulb failure warning system. i have got the towbar and twin electrics but im not sure if i need to fit a bypass relay or not to the 12n side or can i fit a dedicated/specific wiring loom and if i can where will it plug into the car and what will the plug look like?
