Geez! Children!!! hahahahaha
I don't have all my pictures since this was a long ass time ago. This is the first way I did it, to get the wiring to the license plate.
Overview... Of the area with wires everywhere!
Came up the A pillar, and under the headliner and into the hatch through this rubber boot.
Had to get through here, At the time I didn't want to connect new RCA cable to it, so I drilled a hole...
You can barely see the wire running down the very far edge of the door then into the License plate area.
On a side note there is a reverse + signal at the rear view mirror so you don't have to run a lead all the way back. It makes it easy to do this too.
