29861-3 11 Pin Light Harness with Disable Module HB3/H11 Chevy GM 3 Port Truck Light Western Fisher Blizzard SnowEx

This is the 11-Pin Light Harness with relay that comes out of the grille to plug into the plow lights for the 2007+ GM trucks with HB3 and H11 headlights. It is part # 29861-3. If you need the whole kit, this harness came in two different kits - 29400-6 and 52101 (for trucks with LEDs.) 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. The module has been revised a few times. The old single module 29859 is no longer available and you need to update to this harness with dual modules.

This harness is used with 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.
