Trailer Wiring For 2018 Jeep JL Wrangler
Question:
I have a 2018 Jeep Wrangler JL, I recently wired it up for flat towing behind RV. I installed a trailer hitch and I now want to wire it up to tow small utility trailer. Already have the RM-154 Roadmaster Universal HyPower diode wiring kit installed on the jeep, what do I need to add for towing a trailer?

Expert Reply:
The Roadmaster Universal HyPower diode wiring kit part # RM-154 is different wiring than what you need for towing a trailer with the 2018 Jeep Wrangler JL. You will need a 4-pole flat wiring harness part # 118786 which will plug in behind the Jeep's tail lights. You will plug the trailer connector on the trailer into the 4-pole to power the lights. I have attached an installation video for your reference.
