Installation guide fairly easy to follow, towbar bolted straight on to the chasiss, and rear sensor for the tailgate bolted back onto it, so that still works. Feed socket cable through grommet at RHS at this point. 7 pin socket would not swing up, hits rear bumper, bracket has to be extended by 50 mm to move socket back. The Hardest part was taking the rear bumper off the car. Wiring loom for LHS taillights was too short, had to extend that. Loom for RHS taillight was too long. Otherwise connecting the wires to the right BMW wires was straightforward, and it all works. Control box mounted next to RHS Fuse Box. Just need to find PDC controller and disable that on reverse using pink wire, and enable hitch zoom on rear camera. Car tows perfectly, no idea there is anything on the back.
The Towbar ball height is 400mm to top of ball. „
