Western 26345 – 3-Pin Vehicle Control Harness

The genuine Western 26345 Vehicle Control Harness serves as the core truck-side electrical linkage for Western UltraMount and UniMount straight-blade snowplows utilizing the traditional 3-plug Isolation Module wiring system. This essential vehicle-side wire assembly directly connects the handheld or joystick cabin controller to the engine bay’s isolation module, ensuring electrical routing commands are clean and instantaneous. Consequently, fleet mechanics install this authentic factory harness to replace pinned connections that are corroded, green-crusted, or damaged by pests before heavy winter weather hits.

This harness features a precision-molded 6-pin Molex block connector inside the cab to plug directly into your Western 56462 handheld control or 56369 joystick, and extends through the firewall to a heavy-duty, weather-sealed 3-pin round connector at the vehicle bumper. Because severe sub-zero moisture and aggressive road chemicals rapidly degrade exposed copper elements, Western utilizes high-grade insulated wiring protected by a thick, abrasion-resistant outer conduit wrapper. Choosing an original manufacturer-grade replacement eliminates the voltage drops and intermittent signal loss common with budget aftermarket options, preventing the plow blade from locking up or failing to angle mid-shift.

For professional plow contractors and shop mechanics, maintaining an uncompromised electrical foundation reduces complex diagnostics and prevents roadside breakdown situations. This harness installs directly into factory-designated routing pathways, pinning cleanly into your 3-port or 4-port isolation module to preserve your vehicle’s factory electrical configuration and maximize plow up-time.

Benefits of the Western 26345 Control Harness

• Genuine OEM Design: Engineered specifically for Western straight-blade plows utilizing a 3-plug electrical isolation module setup.

• Corrosion-Sealed Terminals: Heavy-duty connector molds lock out fine salt dust and moisture to stop pin oxidation before it starts.

• Direct Plug-and-Play: Eliminates the need for custom wire slicing or inline splicing inside the dashboard or engine compartment.

• Aggressive Signal Continuity: Preserves uniform electrical current across all control points to stop sluggish or erratic cylinder behaviors.

• Durable Outer Conduit Cover: High-strength outer insulation jacket prevents pinching and wire grounding against hot or sharp under-hood components.
