The Western 29049 Harness Kit connects your truck’s H13 headlights directly to the 3-port isolation module. Additionally, this OEM wiring configuration ensures proper electrical routing between your vehicle and the snow plow. Consequently, operators avoid confusing diagnostic codes and flickering headlamps during severe winter weather.
