Hey Robert, whether or not you need the Brake Lite Relay part # RM-88400 is going to be based on the supplemental braking system you are using and the taillight setup of your 21 Wrangler Unlimited.
If your supplemental braking system depresses the brakes of your tow vehicle and your brake lights light up on your vehicle with the key off then you would need it.
What braking system do you have?

I corrected my question but it didn’t go through. Do I need the Roadmaster brake switch to override my factory brake switch
