OEM Western Fisher 3 Port Plug In Harness Kit HB3 and H11 Vehicle Headlight Bulbs

Used on the 3 Port Isolation Modules Only

This is the Truck Side Light Wiring Kit for the 2007 and Newer GM trucks with HB3 and H11 headlights.

This is the newest version, it is the 29400-7. It has been updated from the previous versions. These trucks run the low beam along with the high beams so there is a relay to disarm the low beam in the headlights, so you do not melt your plow lights.

This Kit Includes Light Harness 29499-1 and the 11-pin plow light harness 29861-4. If you are swapping trucks, you need this kit. Both of these harnesses are specific to this truck.
