Did my lighting... Looks sweet! At first I was all over installing the switch, then said screw it. I went easy; tapped straight into grey with no switch, grounded 'em and we're good to go. I started thinking why would I want to turn the footwell lighting on or off??? If it's tapped into the dome light it all controlled there. I'm totally happy with the set up. To all those who contributed and answered my questions... Thank you!
For the video:
(not sure how to load videos here yet)... well, look at that. It worked!
