    I have a 2001 chevy 2500 and i put the wiring harness in and flipped on the light the only lights that i could get on was the high beams. the lows would not even flick. I didnt have the plow hooked up but that should not matter because it would be the same as driving at night in the summer. any one got an idea?

    Was this a used light harness off another truck? Are you sure you have the correct head light adapers? The part# for the adapters for you truck would be: MSC04601

    Make sure the adapters are plugged in on the "A" side.

    look on the plugs the A must match the A on the opposite plug. they can be plugged either way. one way is positive ground other way neg ground

    I thought that A side was for 2003 or newer chevys.

    no lights

    if this is a 13 pin plug smart hitch 2 plow has a two connector plug with white/yellow red/yellow wire the correct orientation for 88-newer gm trucks is red/yellow red/yellow -white/yellow white/yellow.on page 16-17 in the boss installation manual.available on line.

    you may have a problem with the relays if it is a 13 pin smart hitch 2.they run the lights also one for high beam one for low beam.
