Here is a new relay headlight harness for a Chevy or GMC with HB3-HB4 headlights with a Western Unimount. This headlight harness is part # 61716 (8267 from Fisher.) They used this harness from 1988 to 1998. From 88-95 this was used for trucks with no daytime running lights and from 1996-98 the trucks did have the daytime running lights. If you need the wiring kit 61515, we have it listed. Or, if you don't have the power harness, you will need to add that to the cart too. Don't forget to add a tube of Dielectric grease to protect these plugs. This is for 9 pin wiring, not the 12 pin. Make sure you know what lights are in your truck. This harness was used on full-size Chevy's and small Blazer S10's. They must have the HB3-HB4 lights.
