2018 Jeep Wrangler Unlimited Sahara JL Wiring for Flat Towing
Question:
For your 2018 Jeep Wrangler Unlimited Sahara JL flat tow wiring, you will need the Roadmaster Stop Light Switch Kit # RM-751490 which will communicate with your motorhome's brake monitoring system that your Jeep brakes are being applied. This is to help you know if a problem is occurring like your Jeep brakes constantly being applied so you can solve an issue before damage occurs. I reached out to my tech contact at Roadmaster and you will not need the relay # RM-88400 because the factory stop light switch will time-out so it won't remain active when flat towing. For the other wiring, I recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. This will give you a 6-way trailer connector on the front of your Jeep and will allow you to use diodes to protect your electronics while utilizing your factory wires. I recommend also adding the charge line kit # RM-156-25 to maintain your Jeep battery while towing.
