The genuine Western 61438 Plow Harness Kit serves as the essential electrical backbone for your snowplow’s operational connectivity. This factory-original harness plugs directly into your vehicle’s grille plug, routing control current down to the pump solenoids and distributing structural power directly to the plow’s lighting system. Engineered specifically for Western UniMount and early UltraMount straight blade plows utilizing a traditional 2-wire relay system, this plow-side harness ensures seamless integration and control. Replacing a green-corroded, frayed, or brittle wire assembly prevents sudden electrical blackouts before severe winter weather demands active clearing operations.
Constructed from high-grade insulated copper leads and protected by a robust, weather-resistant outer conduit, this 9-pin harness is built to withstand continuous environmental abuse from road salt, liquid de-icers, and intense sub-zero thermal cycling. Because it is an authentic factory-engineered component, it offers versatile adaptability across older fleet platforms. If you operate a 3-plug or 12-pin plow setup, this 9-pin harness can be utilized to convert your system, allowing it to connect safely to a matching 9-pin vehicle harness.
For professional plow contractors and commercial fleet mechanics, maintaining an uncompromised electrical circuit reduces complex shop troubleshooting and eliminates expensive roadside breakdowns. This harness is the exact factory component included in the standard 61540 plow light kit, delivering original manufacturer safety tolerances directly out of the box. Installing a fresh plow-side assembly ensures that your headlamps toggle cleanly and your hydraulic valves respond instantly to your cabin commands.
Benefits of the Western 61438 Harness Kit
-
Genuine OEM Fit: Engineered specifically for Western UniMount and select early UltraMount straight-blade plows using 2-wire relay configurations.
-
Versatile Adaptation: Provides an effective path to convert existing 3-plug or 12-pin plow frames down to a standard 9-pin layout.
-
Corrosion-Sealed 9-Pin Mold: Heavy-duty connector block repels fine salt dust, road grit, and moisture to stop pin oxidation before it starts.
-
Balanced Current Flow: Delivers steady electrical signal continuity to eliminate headlight flickering and sluggish hydraulic solenoid coil response.
-
Durable Outer Shielding: Tough conduit protection prevents physical wire grounding and wire pinching against heavy moving plow components.
