How To Prevent The Brake Lights From Overriding The Turn Signals Of A 2020 Jeep Wrangler Unlimited

Question:

Hello, I have read the QandA’s about this brake light relay and stop light switch RM-751490 but still don’t understand how to stop the towed jeep brake lights from overriding the motorhome turn signals when the brake pedal is pressed. Is there a solution to this for the JL Jeeps?

The stop light switch # RM-751490 you referenced is just for signaling you when the brake is being depressed because the brake light switch wire is either too small a gauge (i.e too weak) to splice into to send the braking signal.

The Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400 is what will stop the braking signal from overriding your turning signals. Since your turn and brake lights are "combined" they use the same wire to activate. This kit just allows the signals to send separately so that the turn signals on your 2020 Jeep Wrangler Unlimited will still work while you're braking.

I've attached installation videos for both kits to aid you in this process.
