Wiring Running Board lites
I have J&J stainless running boards. They have running lights on them. They are Yellow except one on each side at the door is clear.
I wired the yellow(amber) lights to the Trailer clearance lights.
BK/or wire alongside the frame(goes to 7pole trailer plug,comes from relay in PDC. )This was suggested to me by another member.
If you get a short in your handiwork,you only lose the trailer lights it it's hooked up. If it's not only the running board lights.
On the clear ones for the entrance. . I spliced into the yellow wire
behind the headlight switch. Used a relay. (acutally painless module from Geno's).
Now my amber lights on when park or headlights. The clear entrance lights on when I use the remote to unlock the PUor when I open either door. . like the dome lite.
Mine is a 2000 with all the factory options.
This may not be for you. Just thought I would pass it along.
