The genuine Western 72199-1 Harness Kit establishes a stable, dependable electrical connection to operate your snow plow’s headlight towers directly from your vehicle’s factory dash controls. This heavy-duty truck-side lighting kit is an upgraded factory release that replaces the legacy 72168 or standard 72199 layouts. Consequently, replacing a pinched or moisture-damaged loom prevents light dropping faults, ensuring your high and low beams toggle smoothly through freezing winter storms.
This model-specific harness assembly is engineered explicitly for 2019 through early 2022 Chevrolet/GMC K1500 and 2020 through 2023 GM 2500/3500 series trucks. Because this setup incorporates the upgraded 69793-1 11-pin primary wiring loom alongside the 72198-1 plug-in adapter, it utilizes your vehicle’s original factory connectors to achieve a clean shop installation. This design entirely avoids messy custom cutting or wire hacking under the hood. Furthermore, it features newly redesigned, completely sealed internal relays that provide superior protection against water intrusion and corrosive road salt spray all winter long.
This comprehensive master installation kit comes pre-packaged with both critical truck-side adapter cables and necessary matching terminal fuses. Please note that this kit is designed exclusively for standard factory headlamp configurations on specific model years and does not accommodate refreshed mid-year body variations. Utilizing genuine original manufacturer equipment ensures strict electrical protection for your late-model truck’s sensitive computer network lines.
