29400-7 - Western® 3-Port Plug In Harness Kit HB3 & H11 - OEM

This is a Genuine OE 29400-7 3-Port Plug In Harness Kit for HB3 and H11 Vehicle Headlight Bulbs

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

This is for 3-port only.

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. 

This is a direct replacement for 29400, 29400-1, 29400-2, 29400-3, 29400-4, 29400-5 & 29400-6

This part is used on Blizzard, SnowEx and some Western and Fisher plows
