I wanted to add a few photos of how i ran the power to the light. and the seat belt holders. I used a 3/16 or so rod and bent it with a set of vice grips, hammer and a vice. I then just tacked it to the front seat base. I need to pinch them a little more cause they can come out . it was easy and they work. cost about 5$ to make
As for wiring the light . It was a pain to get my wire through the long shell. I had to use a wire puller like a snake, I pulled 2 wires , the hole was 3/4'' and I got the switch at a auto parts place. I run the 2 wires to the switch and then down to the hole in the shell. I grounded one wire there and then poked the other wire down the side where you can see it hanging lose / loose SP? I ran the wire right above where my finger is pointing, at the bend there is a small gap (full of dirt and other stuff) you will need to drill a hole there behind the rubber seal. I had to use a coat hanger to pull the wire through this small hole. then i ran the wire under the rubber to the sill and back up to the front plastic, then I used a circle end ( only kind I had at the point) and pushed it into a open blade hole. It was easy to do and it lights up the back really well.
