Ok so a year or so ago my brother and I installed running board lights on his 2018 F150 tapped into the dome light wiring so they only activate when you open a door or hit unlock on the key fob. I want to do the same thing for my 2021 Ranger but cant find a wiring diagram anywhere to identify the dome light wire. I've tried a voltage tester to try and find it with no luck. Has anyone done this with a new Ranger?
