not sure if this has been asked to death but ive recently decided to think about having a towbar fitted to my above touran 1.6 tdi bluemotion. Should i be aware of any issues when it comes to the wiring side of things? ive heard of issues with damage being caused to the cars electrics due to LED lights etc can anyone shed any light on this for me. Ive got no issues with fitting the tow bar itself just no idea where to start with the wiring with respect to the above possible electrical gremlins. Any help or information would be greatly appreciated along with wiring diagrams
