Mopar Receiver Hitch & Wiring Harness Installation
The only regret I had when I bought my 2017 Trailhawk off the lot is that it didn't have the towing package (everything else was exactly what I wanted). Because I am only going to be using the Jeep to tow small trailers I'm not worried about the lower towing limit. Bought the receiver hitch and wiring harness from my dealer and was going to have them install it, but they screwed up the scheduling and wasted my time so I just did it myself (and saved about $500 in the process). I bought some trim panel removal tools from Harbor Freight to make that part of the work go smoother.
Started with the receiver hitch, followed the directions that came with hitch and removed the rear bumper panel. Had to remove the trim piece over the rear wheels and the tail light / brake light assemblies as well. At this time I also removed the center bezel in the rear bumper panel where the receiver hitch and plug connections would protrude.
The harder part was definitely the wiring harness installation. I followed the instructions that came with the harness. First I disconnected the battery (removed the wire from the negative post), then removed the driver's side trim panels and floor panel / spare tire from the cargo compartment. Then I removed the trim panels along the bottom of the driver's side rear door and front door. Then I had to remove the trim panels located along the lower driver's side of the dash and the lower dash panel located beneath the steering wheel.
I then had to find the rubber boot on the firewall panel separating the passenger compartment from the engine compartment. There is a small rubber nipple that I needed to cut in order to route the power wire to the battery. It was a tight fit to be able to reach it from the engine compartment. I took a photo of the rubber boot from the passenger compartment side. Then I attached the power wire to the battery, it also includes a small fuse box.
I followed the supplied instructions for routing and connecting the wires to the rear turn signals / brake lights. I didn't have to cut a hole in the rear floor of the cargo compartment as there was already a hole cut there that had a rubber plug (I don't have the power lift gate or reverse park bumper sensors). After all of the wiring was in place, I re-installed all of the trim and body panels and everything seems to be working just fine.
