I apologize if linking another forum is in violation of the rules. It's not a Jeep forum. My thread is here
What I did was visit Tech Authority
and open it up in two different browsers (not windows, but browsers). Open it in IE and Chrome. In one browser, enter your VIN. In the other browser, just select a generic vehicle with any trim level that can option out a backup camera. I just chose a fully loaded model. Compare the wiring schematics and connector details of the two Jeeps, and determine what, if any, wires you're missing.
Once you've figured out the missing wires, you'll have to install the wires. Then install the OEM camera hardware. Lastly, have the BCM flashed to recognize the new camera. Flashing the BCM will add the options to your radio automatically.
