Thats the wiring harness Im thinking about buying.

Were going to pull a trailer from Uhaul but not sure of what size an XJ can pull. Our big items are an L shaped couch, lazyboy and a double queen bed. The trip is about 1 mile with no hills. The heavy items from the storage unit are 2 1975 Honda CL360s and lots of boxes about 15 miles slight hills.

I have a class 3 hitch installed mainly for a recovery point right now.

I think I could move everything but the L couch and bikes without a trailer but it would be a PITA.
