Hi, I'm dealing with the same situation, I installed the tow hitch in the dealership, mine is a pathfinder SL 2022 without towing package from manufacture, do I have the same harness? Or what harnesses do I need. I currently have the 4 Pin. I would think that the main harness is pretty universal for all pathfinders 2022. Probably I just need to get some additional harnesses but I can't find any diagrams to change the 4 pin to a 7 and the one to connect the controller. If this is too complicated what do you recommend me? I know there is a universal, but I would think this will be more difficult to do.
