Is the Invisibrake System Compatible w/ a Factory Flat Tow Harness on a 2021 Jeep Wrangler JLU  


Will the Roadmaster Invisibrake work with a 2021 Jeep JLU with the factory Mopar flat tow wiring harness # 82215382AB?


Expert Reply:

Per the manufacturer the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 is fully compatible with the Mopar 82215382AB wiring harness. The wiring harness allows the Jeeps taillights to operate in conjunction with the motorhome's taillights, and would be a separate system that wouldn't have any impact on the operation of the Invisibrake system. You will however need the Roadmaster Stop Light Switch Kit # RM-751490 to pair with the Invisibrake system.

Just to make sure you have accounted for everything needed to flat tow your Jeep I have listed a few other parts that are needed in every flat tow situation.

You will need a base plate kit like the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 which will work with the factory plastic or steel bumper. A tow bar like the Roadmaster Falcon All Terrain, Non-Binding Tow Bar # RM-522 and safety chains like the RoadMaster 68" Single Hook, Coiled Safety Cables # RM-643. You also want to be within 3" of level of the receiver on your motorhome. If you are not within 3" of level you may also need a high-low adapter, I have linked our page of high-low adapters if you end up needing one.
