The Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400 is not needed for your 2021 Jeep Wrangler. This is due to the brake wire being unable to be spliced into. Instead, you'll want to use the Roadmaster Stop Light Switch Kit # RM-751490 if you're going to be using a supplemental braking system.
