Is there no plug next to the tow hitch? I think all or most E70s have the towing module (AHM) but I might not be remembering right. My 2012 had it and had the factory 7-pin connector by the tow hitch.



I installed a brake controller and there is a four-pin plug ready for it. I had to buy pins but other than that it was plug-and-play.
