Reviews for Quadratec Tow Hitch Wiring Harness for 18-24 Jeep Wrangler JL

Works great easy to install!

Easy install. Took just less than an hour. Simple plug and play system no need to splice into the stock wires. I have a 2 door so there was some extra length of wire so I just looped it and tied it up away from the exhaust near the brake booster. Would definitely recommend as a simple way to add 4pin harness.

Easy install

Work great and for the price cannot beat it. Had a local place install it for about $100.

I installed this on my 2025 JL 2dr Wrangler sport. It took about an hour and fit perfectly.

Exactly what I needed to run the lights on my small utility trailer. Easy installation, can be installed by someone with little to no experience. Although the directions are good, one tip that I would add; make sure to route the harnesses ends over the frame behind the rear shocks before going into your tail light housing. Completely hidden install that is clean and looks like it came installed from the factory on my 2019 JL Rubicon.

Although the video and instructions were great, I still took it to my local trailer shop to have it installed since I also needed a 7 pin connector added to the included 4 pin. This harness is 1/3 of the price Mopar is charging.

Just finished the install…. Super easy! Maybe took an hour… with beer breaks.
I haven’t hooked it up to my jet ski trailer yet, but I am certain it will work. My ONLY complaint is that I bought the Quadratec trailer hitch a few years back. My original intent was was to use it to attach my MTN bike rack. Well, a jet ski later,

EASY install!! Just remember, the harness that runs forward needs to go down the Driver's side. I needed this in a hurry and Quadratec came through right on time, THANKS!

Good quality, fits good and easy to install
