Greetings All,
We have a 2016 22FB and love it! I'm installing backup lighting using 2 sealed led units installed in the bumper. I want to connect to the center pin (which seems to be the backup power on the plug).
In looking under the bed, I think I've found where (Ithink) the cable from the truck comes up inside from the frame. etrailer.com had a pinout which says white wire is ground and purple is backup.
Of course, there's no purple wire in the bundle coming up out of the floor.
I'm going to get a helper to apply
12v to center pin of coupling to camper while I'm inside with meter.
Any suggestions?
