Year/Euro/US will make a difference although electrics are electrics, they can get confusing. I hate electrics, but sat down with a few different wiring diagrams and learned the basics so that trouble-shouting the mess of early, late bay and aftermarket wiring/parts in my bus is now easy...er :lol:
