Once you reinstall all of the covers and put the torx screws back into the tag light/handle lip you now need to wire the camera in. Sorry I don't have better step by steps on this but I was dead tired at this point since I had tried several other mounting methods before this and it took all day and most of the night. Using this method it should be installable in about 60 minutes.

For the wiring I did everything at the seicanes harness plug where it connects to the factory harness at the old radio module in the bottom of the hatch area.

The video plug part plugs into the seicane provided rca plug and the power and ground I tapped right at this plug too. I used the same wire that turns the amp on to power the camera. The reason for this was to allow me to use the camera when not in reverse.
