Turn Signal on 2016 Jeep Wrangler Stops Working When Brakes are Applied on RV

Question:

I installed your Roadmaster wiring kit with diodes in our 16 Jeep Wrangler which we tow behind a 16 Sprinter 3500 Winnebago motorhome. The Jeep rear turn, brake, and running lights are wired into a 7 pin plug that attaches to the motorhomes factory installed 7 pin connection. All functions appear to work properly with one exception. After activating the Sprinter turn signal, when I apply the Sprinter brakes the turn signal stops. Brake lights remain on but without the turn signal. This is the case for both right and left turn signals. The tow brake installed in the Jeep operates as it should when I depress the Sprinter brake pedal. Might you give me a bit of advice to remedy this situation? Thanks so much.

The solution for your 2016 Jeep Wrangler flat towing situation is the RoadMaster Brake-Lite Relay Kit # RM-88400.

The Brake-Lite Relay Kit will keep the your Wrangler's brake signal from overriding the turn signal which comes from your RV.

I have attached a demonstration video of this relay kit being installed on a similar 2016 Jeep for you to use as a reference.
