I am having problems with the running lights (tail lights) not working on my trailer. The pin on the wiring plug has no power to it. The turn signals and brake lights work normal. I did find a blown fuse #27 (Trailer side lights) in the passenger compartment Fuse block. I replaced the 10A fuse and expected that would cure the problem but no luck. I did check all fused where trailer is in the description but did not find another blown fuse. Does anyone know or have access to a wiring diagram that could tell me if there is another fuse in that circuit or a relay controlling the power to it. Any help or words of wisdom would be much appreciated.
