New to the site, if this is the wrong place let me know.
My truck is a 2003, 2500,4X4 w/ Cummins engine. I have a situation that I cannot seem to resolve, all lights on the truck operate correctly but I have no left turn signal or emergency flashers on the trailer. The trailer is a brand new 20 ft tilt. I checked the circuit at the connector going to the trailer connector and have no output for the left turn, right turn works OK. are the trailer circuits different from the truck turn signal buss? And is each side provided it's own circuit? Any help appreciated, Patrick
