what do I need to install a 7-way to my 2021 Jeep Wrangler JL?

Expert Reply:
As far as installing a 7-way to your 2021 Jeep Wrangler JL, you need to have a 4-way harness installed already. If you need a 4-way, that is the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786. The T-One includes a ModuLite power converter to ensure that your vehicle's wiring matches that of your trailer. If you are looking to add a brake controller to the trailer, you will need the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat # ETBC7 in addition to the T-One.
If you are wanting to add a brake controller, I recommend the Tekonsha Voyager # 39510 or the Curt Echo # C51180. Both of these controllers are proportional controllers which means that the controller activates the trailer brakes in proportion to your vehicle's braking action. The Voyager is more of a traditional-style controller than requires mounting into the dashboard of your vehicle near the steering wheel. On the other hand, the Curt Echo allows you to control the settings of your controller with the ease of your Smart device.
If you need help installing any of these accessories, I went ahead and linked walk-through videos to guide you through the process.
