In order to install the Blue Ox Tail Light Wiring Kit part # BX8869 in the back of the taillight housing on your 2017 Jeep Wrangler you will need at least 1" of space in order for the bulb and socket kit to work. I did some research and looked at a few of the taillight assemblies for your Jeep and believe you should have absolutely no problem using this kit.

1) Starting in the engine compartment of the towed vehicle, run the 26 ft. harness through the fire wall, under the driver's side door sill plate, under the back seat, into the trunk area or run harness through engine compartment and beside frame rail to the back of vehicle. Depending on the motorhome set up, the wire at the front of the engine compartment should be wired into either a 4-wire or 6-wire trailer plug that is mounted to the front of the towed vehicle.

2) The bulb and sockets are installed into the back of the vehicles tail light assemblies. The location should be as flat as possible, with enough clearance for the bulb on the inside and the socket on the back side. Using a 1" hole saw, drill a hole into each housing at the selected location.

3) The black wire is the brake/ turn signal wire and the brown is the tail light wire. The white wire is used for the ground wire.

4) Insert the bulb and socket into the 1" holes by gently pushing them into place. Seal socket to tail light housing with a good silicone caulk.

5) Run the black and brown wires from the passenger's side socket to the drivers side where the four wire loom is.

6) Crimp the three brown wires together. Now crimp the green (turn signal/brake) wire from the four wire loom, the green 8 foot wire and the black (brake/turn signal) wire from the passenger's side together. The white (ground) wires should be grounded to the frame with ring terminals and self tapping screws. The white wire from the four wire loom should be connected with the white wire from the driver's side socket then grounded.

7) At the driver's side socket connect the black (brake/turn signal) wire and the yellow (brake/turn signal) wire from the four wire loom.

8) Place the wires out of the way. Test the system before attaching the tail light assemblies back onto the vehicle. To test the system, a 4-wire or 6-wire trailer plug must be installed on the front of the towed vehicle using the 4-wire harness installed. Once installed, plug the vehicles together with coach and test each turn signal and the brake lights. If lights do not work properly, there must be a loose connection, or a wiring error. Recheck to assure all connections were made correctly, especially the ground connections.

I have also attached an installation video of this harness installed on a somewhat similar vehicle for you as well.
