    Hi, I am a newbie here and need help! I bought a used fisher mm 7'6" for my 2000 silverado 1500. It came with the 4 port isolation module with all the wiring harnesses & hand held controller.
    The headlight harness are for HB1. Can I just buy the Gm harnesses for HB4 headlites & plug them in to that module Ports 3 & 4 ?? How do you piggy back the plugs on ther harnesses to the OEM plugs? Is there another way of just operating the Plow lights with a different switch? Any Help would be appreciated. Thanks, Mike
