In order to install a functional 7-way trailer connector on your 2015 Jeep Cherokee, you'll first need to install a 4 pin connector to access the lighting circuits. I'd recommend part # 118605.

How you proceed from here will depend on what you are towing. If you are towing a trailer that has a 7-way trailer connector but does not have brakes and does not need a constant 12-V power feed for keeping a trailer battery topped off or for minimal interior lighting, you'd also need the # 37185 adapter which would plug into the 4 pin connector supplied by the # 118605 mentioned above. The adapter has 4 additional wires, the only one you'd need to use is the white ground wire, which should be attached to the frame or part of the chassis that's in contact with the frame. The adapter will provide both a 7-way and a functional 4 pin connector.

If your trailer does have electric brakes, you'll need to take the install a little further. In addition to a brake controller like the Redarc Tow Pro Liberty, part # RED24FR and the wiring pigtail, part # RED69FR. To complete the installation of the controller, you'll also need our # ETBC7 brake controller installation kit. The kit includes the # 37185 adapter mentioned above, as well as all the wire, circuit breakers and hardware needed to successfully complete the installation. You'll ground the white wire on the adapter as described above, but the blue wire on the adapter would extend to the passenger cab to carry the brake controller output, and the black wire would run to the vehicle positive battery to provide a 12-V feed to the trailer when needed.

I've linked to an install video for the # 118605 wiring harness, as well as to some demonstration videos that explain how the brake controller and the install kit I mentioned works.

You can try fitting the Stromberg Carlson Trailer Tray Cargo Carrier #CC-255 sideways but it wasn't designed to be installed that way so I recommend installing it the correct way and routing your wiring to it that way. This will fit A-Frames…

Basically a lot depends on what you will be using the hitch for. If it is just for accessories such as a bike rack or cargo carrier than for the most part you will be fine with a Class II trailer hitch. If you will be towing then I would go with…

Hey Antoine, so the two kits you mentioned are actually really similar and honestly I would go with the part #ETBC7 if I were you. The #ETBC7L is basically the same thing minus a couple wires and breakers so you may as well get the kit that has…

If you have a vehicle specific wiring harness for a brake controller then that would indicate that you have a factory tow package and subsequently would already have a 7-way at the back of your vehicle. The universal 7-way connector #ETBC7 is meant…
