As the title says. I successfully completed the install in my 2014 Cherokee Limited V6 4x4.
All parts bought from E-Trailer.
Curt class III hitch, Cherokee 4 Pin Harness, Universal Brake Controller Kit and P3 Brake Controller.
Installing the hitch and 4 pin are easy and there are videos on Etrailer for this car.
There are no Videos for installing the Brake Controller nor wiring.
If you watch a video of another newer model vehicle it will give you a basic idea of how to run the wiring and setting up the new 7pin/4pin connector at the rear.
The hard part is getting to the Cold Brake Wire. This is the wire that tells the controller that you are applying the brakes.
If you get upside down in the drivers foot well and look up you will see a blue adapter with a white top and has four wires coming out of it above your brake pedal. This is the brake switch. If you give it a quarter turn it will come off and give you room to strip back the wire coverings. The brake switch is self calibrating. So when you put it back in place (DO NOT PRESS ON THE BRAKE PEDAL)
There are 4 wires. You only want to use the Green Wire with the Light Green stripe.
FYI: There is another green wire but it has a neon yellow stripe. Very easy to get confused.
Not gonna lie, it was not easy getting up there. The harness is pretty high in the dash and its really hard to see. Its a little tricky getting the blue brake switch back in place, but it can be done. You can't see so you have to go by feel. Get it back in the slot, make sure its sitting flush and quarter twist and its locked in place.
