Just saw this question, and even though it's 3 months old now, I'll reply anyway. I have installed a reverse camera in my FG X ute. I bought the kit from ASL and ran all the wires from the camera, under the car and into the cabin myself. I then paid an auto elec to hook it into the ICC. It's basically a couple of wires with pins that hook into an existing plug under the top cover. Once hooked up, a plug is inserted into the OBD port to flash the module into the car's computer. Wasn't cheap but works like factory setup when reverse is selected.
