Question:
I want to install the Tekonsha P3 in my 2022 Jeep Cherokee. Which install harness is needed? I have the 7-pin socket on the back bumper.

Since you have the tow package, you'll have an easy install. You'll need the # 3014-P brake controller harness that would plug into the factory tow package connector located behind and to the right of the OBDII connector, as shown in the provided photo.
Can I make a suggestion if you don't already have the P3 brake controller?
If you'd rather not have a controller mounted to the underside of the dash where you can bang your knee on it when entering and leaving the vehicle, you might find a remote-mounted brake controller to be a better option for you. The Redarc Tow-Pro Liberty, part # RED24FR actually mounts behind the dash so it's out of sight (and out of the way). You'd adjust the controller using the small control knob that can be installed anywhere within easy reach of the driver. An unused switch knockout in the dash makes the perfect mounting spot but if one isn't available, a mounting bezel like # 331-TPSI-001 would make for a neat, factory looking install. You'll also need the # RED67FR harness.
I've linked to a video showing how the Redarc Tow-Pro Liberty brake controller works.
