This is the truck side headlight wiring harness for the 2007+ GM trucks with HB3 and H11 headlights. This is for 3-port isolation module only. The part # on the harness is 29499 and it comes from kit 29400-6. This kit has a special harness, because this truck runs the low beam along with the high beams and they installed a relay to disarm the low beam in the headlights so you do not melt your plow lights. If you don't have the correct light harness 29861, you are better off buying the kit.
This is for Western, Fisher, Blizzard and SnowEx.
Western went from relay wiring to 4-port wiring, to 3-port wiring and now Multiplex wiring. We have all of these options available. We will also trade in your old wiring.
