There are a few questions to consider in order to determine whether your 2022 Jeep Wrangler will require a brake light relay like part # RM-88400. I included this question tree to guide you through those questions:

No - You do not need a brake light relay.
Yes - You may need a brake light relay. Continue on to the next question.
Do the brake lights on your towed car illuminate while the engine is off?

Do your towed car's brake lights act as both the brake signals and the turn signals?

Yes - Your towed car has a combined lighting system. You will need a brake light relay to ensure proper activation of its signal lights.
Does your towed car have separate brake lights and turn signals?

Yes - Your towed car has a separate lighting system. You may need a brake light relay. Continue on to the next question.
Are you wiring your vehicle with a six-diode kit or a TowDaddy custom wiring harness?
