2010-2012 Range Rover MkIII / L322
Last week I installed the trailer wiring harness (VPLMT0008) for $135 and it took under 5 minutes and the easiest thing to do. I read that the dealer would need to activate it...but that is incorrect. I called them and they said it's already active and the only thing they do is disable the back up sensors. So pretty much, it's a waste of labor. I can simply press the button to turn out the sensors. Installed the receiver and ball, picked up my trailer, plugged in the 4 pin adapter and lights came right on and tested everything. Picked up my boat and I'm a happy camper.
