Mopar wiring harness on 2020 Wrangler

I currently have a 2015 2 door Wrangler setup to tow behind our motorhome. My wife's old 2014 4 door Jeep was also setup to tow. She traded in her Jeep last year on a 2020 and it's not setup yet for towing. I miss being able to take her 4 door on some trips when we have our nieces with us. The 2 door is very cramped.

On my 2015, I have the blue ox baseplate and I have the mopar wiring harness for the lights. Does Mopar make a wiring harness for 2020 Jeeps? When I search, I find the same harness that I purchased for our 2015 but I have been told that harness won't work with the JL Jeeps (2018 and up).

    You may need also need the harness that enables EPS when being towed. Call the dealer to see if it's available.

    Search death wobble on irv2.com for a ton of information.

    I don't think these are needed on Wranglers but I have heard about the death wobble on Grand Cherokees. I think the electric power steering might be different between the models but I will definitely check.

    Wranglers have a different PS system. Same type recirculating ball, but the fluid uses an electric pump. So no special harness needed.

    Not sure on the specific light wiring harness.

    The Mopar wiring harness is 82215382AB. It is a lot of work to install and you have to be careful with the electrical plugs since the directions are not very clear, but it works well.

    I used the Cooltech harness on our 2012 Wrangler, but the current harness requires you to remember to flip a switch.

    Wow, they are pretty proud of that wiring harness. Over 3 times what I paid for the 2015 JK harness.


    Thanks for the info.

    I came to the same conclusion, so I went online and bought a 25 foot coil of 7-conductor wire, in a sheath, for about $35, and two 4PDT switches for about $5 each and I'm building my own version of their harness, for my Gladiator AND my wife's Wrangler!

    That would certainly be cheaper. I bought the Blue Ox kit from Amazon, Blue Ox BX88368 EZ Light Wiring Kit for Jeep Wrangler JL & Gladiator, for my 2021 JL.
