JUST BOUGHT NEW 6X12 UTILITY TRAILER AND PLUG ON TRUCK NOT WORKING I HAVE TURN,BRAKELIGHTS BUT NO RUNNING LIGHTS ANYONE HAVE ANY IDEAS OF WHAT THE PROBLEM MIGHT BE.THANKS

 

Are you positive its the truck? use a DC meter and test each lead on the truck plug to the ground--i forget which one is the running lights, but usually a brown wire (you must have the corresponding function on in your truck). Is the trailer plug a 4, 6, or 7 way? I wouldnt think too many 6x12 trailers would have a need for more than a 4 pin connector. Could be the converterter your using from your truck to match the trailer.

 

If your trailer has a 4 way plug then look under the bumper to the drivers side, there will be a 4 prong plug just hanging there just for that reason. My .02 worth. ;D
