The genuine Western 29051 Headlight Plug-In Harness Kit serves as the critical vehicle-side electrical connection designed to adapt your truck’s factory headlight configuration to Western’s advanced 3-port isolation module systems. Engineered for vehicles running traditional 2B, 2D, or HB-2 headlight bulbs, this comprehensive wiring pack handles the seamless cross-transfer of high and low beam signals from the truck cab out to the plow lights. Consequently, fleet mechanics install this factory-authentic plug-in harness to replace green-corroded pins, frayed wires, or intermittent headlight circuits before blinding winter blizzards call for commercial snow clearing.
This high-performance kit includes both the primary 28464 plug-in headlight adapter and the heavy-duty 29861-4 11-pin vehicle lighting harness equipped with an integrated fuse and relay network. By providing a dedicated electrical pathway that isolates and draws power safely without overtaxing sensitive vehicle dashboard modules, this factory setup completely prevents computer fault codes or flickering headlamps. Because severe under-hood thermal cycles and liquid de-icers rapidly ruin low-grade aftermarket wiring, Western wraps this harness in a high-grade, premium insulation jacket that completely rejects moisture and fine salt dust.
For professional contractors and operations managers, ensuring crisp electrical communication means less troubleshooting in the middle of a major winter event. This genuine OEM assembly plugs directly into your existing vehicle sockets and the 3-port isolation module, preserving the truck’s standard electrical architecture and removing the need for dangerous field wire cutting. Installing this complete kit guarantees that your vehicle-to-plow lighting swaps function instantly, every time you attach the blade.

Had to cut the connectors off and hard wire but I think I gave the wrong information. I still got everything to work.
