Will the Stop Light Relay Be Needed When Using Supplemental Braking on a 2015 Jeep Wrangler


I am going to tow a 15 jeep wrangler unlimited. I installed the Hopkins harness and am going to use an RVI 3 brake system. Do I need a brake light relay?


Expert Reply:

Yes, if the supplemental braking system uses the brake pedal to apply your 2015 Jeep Wrangle's brakes, then you will need to wire in the Roadmaster Brake Relay, # RM-88400.

The relay will keep your Jeep's brake light signal from overriding the turn signal coming from your RV. The will bypass the brake signal to allow which every turn signal you have on to not stop blinking when the brakes are applied.

I have attached an installation video that will show this relay being installed on a 2016 Jeep Wrangler Unlimited. The installation will be the same on your 2015 Wrangler.
