Hey Buddy, Thanks for your help. I may be stupid but as you hopefully can see rom my poor photo's, my connector has 5 wires total in it. In position 1 its black, position 2 its gray, position 3 its green/white that's the top row. then on the bottom row, its purple/white in position 9 and yellow/purple in position 10. (and oddly enough, position 1 which is black, seems to have the most voltage.) Seems like everyone says this is the ground. My test light glows bright red on this position???
I used a mirror tap when I installed this same mount in my Cadillac and it was very easy. One wire was hot and the black wire gave no power signal at all. That's why I'm confused-ha!
