Hey Guys, I installed puddle lights under my running boards and tapped into my reverse lamp to come on when the doors are unlocked and when I place it in reverse. I also want them to come on when the doors are open. I realize I'll need to install a diode to prevent the backup lights to come on. Does anyone have an idea where to tap into without dismantling all the trim work? I read the door handle has a switch to activate the dome light and probably an easy reach if I had a color schematic for the wire harness. Any ideas or help would be appreciated.
