8443 Western Fisher 4 Port 3 Plug Wiring Kit Isolation Module Truck Side Light Harness Kodiak Topkick GMC 4500 5500

The Truck Side Light Wiring Kit for trucks 90-96 Kodiak and Topkick and the 97-2002 Chevy and GMC 4500/5500. The part # on this kit is 8443. We have all the others available, too. You get the 4-port module 26400, 26357 truck side 11-pin light harness, light harness 26638, 50" battery cable 20681 and parts bag 26395, 26661, and 26662. If you are just swapping trucks, you probably only need the light harness and not the complete kit. But if you need a module too, the kit is the best deal. This is the same for Fisher and Western. This is the 4-port isolation module and the 3-plug set up.

Western went from relay wiring to 4-port wiring, to 3-port wiring and now Multiplex wiring. We have all of these options available. We will also trade in your old wiring.

We recommend getting a tube of dielectric grease to protect these plugs.
