OK,
I shorted out my running lights on the trailer by plugging it in while the truck was running, I misaligned the connection and it messed it up.
Brake lights are workning fine but the running lights are not on.
Bulbs are OK,
Anyone know what color wire powers the running lights?
I'm guessing I burned a wire.

PS, truck lights are all good, and I checked all the fuses on the truck just in case.
I can't find a fuse on the trailer, It's a 4 wire system.
thanks,
Brett
