63392 Western Unimount 99-02 Chevy GMC HB3-HB4 9 Pin Control Wiring Harness Fisher 26070

Unfortunately, as of Jan 2012 this kit is now discontinued from Western. We have a few left & will list more if we come across them. The DRL heat sink is not available, so once these are gone you will be forced to convert to 3 plug wiring.

WE HAVE come up with a replacement kit at this link 63392 Replacement

The Western Part # is 63392 and Fisher # 26070. Here is a new wiring set up for a 1999-2002 (new body only) Chevy or GMC with HB3-HB4 headlights with the Daytime Running Lights for Western Unimount or Fisher Relay style wiring.  (*NOTE there are some 99-01 trucks that are still the old body and this is not the right wiring, they would look like a 98 truck.)  This comes with the 9 pin relay style control harness 61437, headlight harness 26071 Western and parts bag 63395 and 61559. They also offer a short kit that gives you everything for the light wiring but no control harness listed here for those that are just swapping trucks. If you don't have the power harness you will need to add that to the cart too. If you only need the light harness we have them listed also, set up to run the day time running lights. Make sure this is the correct kit for your truck, it only fits HB3/HB4. Don't forget to add a tube of dielectric grease to protect these plugs.

To make sure you are getting what you need you can use this Wiring Schematics guide use page 65.

The instructions for this wiring kit can be found here.

Fits:

99-02 GMC & Chevy 1500 Truck

99-02 GMC & Chevy 2500 3500 Trucks
