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. 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.
