I’m not getting running lights on my trailer. Checking the list of fuses in the manual and don’t have a clear answer of what to check. Have stop, left and right turn. Do any of you gurus know what I should be checking?
Truck is 2011 CCSB 6.7L

Problem for me is usually wiring or connections on the trailer.
Check the plug on the trailer for corrosion, and if that's ok check the wiring and connections on the trailer especially if its dunked in saltwater. Brown wire is usually for the running lights.
Thanks for all the helps guys. There is clearly a short somewhere on the trailer. I think it is within the fold down door. The 30A fuse #26 did keep blowing. When I originally checked it the fuse looked OK but once I put my test light on it that's when I figured it out. Without the trailer power to the pin. Gonna have to trace the wire and find if it is grounding out somewhere.
