7 Pin Wiring Schematic on BMW Hitch
I am trying to ascertain what the wiring diagram is for an installed BMW Hitch 7 pin connector. There were no sheets left with the vehicle after they installed the BMW Hitch and 7 pin connector with the factory wiring. Tried on line to no avail and dealer not much help either. I want to make sure that when I hook up our travel trailer to the BMW the wiring from BMW 7 Pin & Trailer 7 Pin are compatible. We also just got the BMW Brake Controller installed and we did not have to loos a cup holder. They mounted it on the left under the headlight control switches....Serv Mgr said there was plenty of wire to run it to that location.
Thanks for any help
