    The Fisher I bought this summer came off a 2001 GMC, I put it on an 06. I had the same problem. Where the factory light harness plugs into the plow harness, the wires weren't matched up. Say it is a red and black wire, the red on one end plugged into the black on the other end. I pulled the wires out of the plow harness and switched them around and all is good. Take a look at the wires and make sure they match up, I would think it would be color coded.
