western wiring issue

    I took the wire harness of my 2002 chevy 1/2 ton and put it on my 2003 HMC yukon. Everything plugged in fine. When I plugged the plow in my headlights went out on my truck and just the parking lights went on on the plow. In order to get my lights back on the truck I had to disconnect the switch over plugs right from my original headlights. Obviously I fried a relay. Why? Is it possible I had the low and hightbeams reversed? Would this cause it? Thier was corrosion on the Plowside plug also.

    Possibly you just had the headlamp harness plugs flipped. If they are two wire plugs then you have to flip them 180 degrees if the plow lights don't come on. It's just a matter of getting the common wires together. Maybe the relay is not fried...
