Do I Use The Brake Light Relay Or Stoplight Switch In 2019 Jeep Wrangler For Supplemental Braking


On a 2019 Jeep Wrangler JLU with push button start, how do I stop the auxiliary brake from overriding the turn signal? Do I still need the Roadmaster break relay kit?


Helpful Expert Reply:

You will need the Roadmaster Stop Light Switch Kit part # RM-751490 on the 2019 Jeep Wrangler according to Roadmaster if you are installing a supplemental braking system that utilizes the stop light switch to activate. The factory stop light switch in the 2019 Jeep Wrangler times out after a certain time being flat towed.

You will no longer need the brake light relay kit part # RM-88400 because the brake light switch kit will now keep the Jeep's brake signal from overriding the turn signal of the RV. Please keep in mind you will also need the 12 Volt Outlet Kit # RM-9332 depending on which braking system you are using.
