Hi I have a 2017 f150. I want to install running board lights. I need to find
1- right turn signal wire
2- left turn signal wire
3- courtesy light wire
4- running light wire
I was told if I pull off the passenger rear sill plate there is a wire harness in there that has everything I need does anyone have the wire colors for what I'm looking for?

Might be best to use the trailer wiring for the running board lights...left turn, right turn, park/tail. If wired to the BCM outputs, the BCM could see additional load as a fault and shut down those particular outputs. Do the instructions state power consumption for the various lights?
