Expert Reply:
The first thing you will need for your 2021 Jeep Wrangler Unlimited Sport is a 4-way. I recommend the T-One Vehicle Wiring Harness # 118786 since it is the most reliable. This will plug in behind your tail lights and provide you with a 4-way for your trailer's signal lights.
Once you have installed the 4-way you will need the Universal Installation Kit for Trailer Brake Controller # ETBC7. This comes with the adapter, wiring, and everything else required to upgrade your 4-way to a 7-way. However, using this combination means you will need to hard wire your brake controller. This will not interact with the factory port under your dash.
