The genuine Western 74973-1 Headlight Harness Kit is the essential electrical solution for integrating your snow plow’s lighting system with your 2020-2022 Ford Super Duty truck. This harness kit is engineered for factory-standard Quad H13 halogen headlights and supersedes the earlier 74973 part number. Consequently, it streamlines your installation process by including an integrated “key-on” power wire, eliminating the need to manually splice into the vehicle’s accessory circuits.
This high-performance harness kit is designed for complete compatibility with Western, Fisher, and SnowEx FleetFlex plow systems. By utilizing a 16-pin connector design, it interfaces directly with your truck’s headlight architecture, providing reliable power and crisp signal transmission. Furthermore, the robust, weather-sealed casing guards your plow’s vital connections against sub-zero temperatures, salt spray, and winter debris. Therefore, you can maintain reliable lighting performance and avoid common electrical faults even in the harshest clearing environments.
This kit ships complete with the necessary 26357 vehicle lighting harness (11-pin) and the specialized 74972-1 plug-in harness (16-pin). Please note that this kit is specific to halogen-equipped trucks and is not compatible with factory-installed LED headlight systems (for LED applications, please see kit 74993-1).
