You will need to create a wiring harness from the head unit to the tailgate ( it won’t have the wiring ready, unfortunately).
I ended up going to the wreckers and cutting the harness out of a vehicle (to get the plug to fit the camera). The harness is also tapped into reverse lights to indicate to use camera.
You will also need to cut some metal to fit the camera where the old badge is.
I also fitted a time delay circuit so that the camera is fully extended before showing the picture on the head unit. The head unit powers the camera (takes signal from reverse light) so the delay timer sends signal to head unit after approximately 1 second after putting into reverse.
