First, as far as the wiring goes, I ran it pretty much the way Lex did. So, I will no bore you guys again with those details. The wires from the monitor go down towards the kick panel. Remove the door seal near the hinge and you will see it is easy to get behind the plastic to hide wires. There is a good ground near the floor there and power for the monitor comes from fuse 15 ( climate control ). Here are some pics:
What you will need to do to the trim panel to get it to fit. Rotary file on a drill or a Dremmel tool works great.
Camera installed on trim panel.
Another view mounted on trim panel.
Camera and panel installed ( I know, it needs a bath ...)
