Hello Gary, thanks for getting in touch. The Curt # C13392 is indeed a fit for your 2021 Jeep Wangler Unlimited JL. The correct wiring harness is the Curt T-Connector # 56407, which will give you a 4-flat connector. You will also want the # 18144 bracket to complete your installation.

Hey Gary, how did the wiring setup go with the Curt T-Connector on your Wrangler Unlimited JL? Your update could make it easier for the next person adding a hitch and wiring to the same model.
