Installed running board lights. Tied in to the cargo light wire so they are only on after unlocking with key fob, opening a door or pushing the cargo light button.
(White wire with green stripe under rear driver side door on the 2021 anyway, for anyone curious. Wasn’t easy information to find.)
A couple years ago my brother and I installed LED strip lighting above his running boards on his f150 that would only be on when you open a door or hit unlock on your key fob by tapping into the courtesy light wire. I’m wanting to do the same to my 2021 ranger but can’t find a wiring diagram...
