The genuine Western 26357 Truck-Side Lighting Harness is a critical component for maintaining your snow plow’s electrical integrity. As an essential part of the lighting system, this 11-pin harness carries power and signal commands from your vehicle’s electrical network directly to your plow-side lights. Consequently, replacing a corroded or damaged harness prevents common issues such as flickering headlights, intermittent turn signals, or “dead” plow lights during critical winter storms.
This factory-spec harness is built to withstand the harsh conditions of winter work. Featuring high-quality, weather-sealed terminals, it effectively blocks moisture, road salt, and corrosive chemicals from reaching the internal copper conductors. Because it is a genuine Western component, it is engineered for a precise “plug-and-play” fit, eliminating the need for splicing or custom modifications that can compromise your vehicle’s factory wiring.
This harness is designed for compatibility with standard 11-pin Western lighting systems. Whether you are performing a seasonal preventative maintenance check or replacing a failing harness, installing an authentic Western 26357 part ensures your plow’s front lighting operates exactly as intended. Keeping this connection clean and fully functional is vital for remaining legal and visible on the road.
