64075 Western Unimount 03-06 Chevy GMC HB3-HB4 Headlight Harness

Here is a new Headlight Harness for a 2003+ Chevy or GMC with HB3-HB4 headlights with the daytime running lights for a Western or Fisher relay style wiring (part #64075.) This system uses 6 relays and you must have a 12 pin control harness and 12 pin lights for the lights to work. If you want the complete kit, it is 64077 for straight blade and 64085 for the older V plow. If you don't have the power harness, you will need to add that, too. This is set up to run the daytime running lights. Make sure this is the correct kit for your truck, as it only fits HB3/HB4. If your plow side is 9 pin and you want to move it to this truck, you will need to get the 12 pin plow side harness listed here.

Don't forget to add a tube of dielectric grease to protect these plugs.

The instructions for this 64077 wiring kit are here.
