We've got just what you need. If you don't already have a 4 way connector on the back of your 2020 Jeep JL you'll first need to install that using the Tekonsha T-One Wiring Harness # 118786. This harness will tee into your Jeep's tail lights and provide you with the starting point for installing a 7 way connector. If you've already got a 4 way, you're halfway there.

For a 7 way connector you'll want to use the # ETBC7, which will utilize the wiring already in place (or newly installed with the 118786) and provide you with a 7 way connector that will power the electric brakes on your cargo trailer. If you don't already have a brake controller, I recommend using the Tekonsha Prodigy P3 # 90195 and adapter plug # 3073-P which will provide proportional braking for your trailer in one of our most reliable and highly rated brake controllers.

I've linked some helpful installation videos of these parts on similar Jeeps for you to have a look at as well.
