    Helping brother in law with light problems on 2011 gmc 2500. He has a wideout. When hooked up right side works fine. Left side has no low beam on truck or plow and when switching to high beam tuck light comes back on and no plow light. Two relays in harness buzz until I unplug the plow light bulb. I have swapped modules, tried new main plug harness on truck end and even the head light harness. Nothing changes....I'm stuck! Any suggestions would be great!!

    Try switching the plow to trk.headlight plug from A to B. Or 180 around and see if that helps

    I think what Dss means to say is go behind the RH headlight. You have a quad headlight system and both the high and low beam plugs are backwards. Disconnect the Western harness plug from the truck low beam light plug and flip it over. Do the same with the high beam. The original truck plug is keyed but the Western plug is not so you can try it both ways effectively flipping the wire connections. One way works and the other way does not. Truck lights usually work regardless but the plow lights only work one way. Leave the plow connected when you do this and you will see the plow lights start working.

    Yep that was the problem! He had some bodywork done this summer and when they put headlight back in they had the plugs messed up. He done all the trial and error work before I got there. Once I started looking at the wiring and plugs on the headlights I found the issues with the plugs. Thanks for the help!! Let it Snow..Let it Snow!!
