Western 78402 – Spreader Vehicle-Side Harness Kit (FleetFlex System)

The genuine Western 78402 Spreader Harness Kit establishes the foundational truck-side electrical framework necessary for commercial material spreaders. This heavy-duty 8-pin vehicle wiring master loom connects directly to your truck battery and in-cab remote system, running cleanly out to your rear bumper. Consequently, installing a fresh factory wiring kit ensures flawless communication lines between your cab remote controls and the high-amperage hopper motors. It eliminates sudden material feed dropouts during severe winter conditions.

This master package is engineered explicitly for contemporary FleetFlex multiplex dual-motor layouts. Because it aggregates main conveyor, auger, and spinner commands into a unified data stream, it eliminates legacy wiring bulk under the hood. Furthermore, it features completely weather-sealed terminal plugs and high-tensile over-molded casings designed to block out water intrusion, corrosive road chemicals, and liquid brine spray all winter long.

This complete master installation package provides a reliable shop setup by including all matching factory sub-harnesses. The comprehensive kit bundles the 69902 interior control harness, the 76057 primary vehicle power cable, the 22511 high-draw battery wire, and a protective 99759 rubber plug cover. It also contains a robust 95836 100-amp fuse and the companion 95837 fuse holder/isolated stud block. Please note that this kit is specific to modern FleetFlex configurations and will not function with older pre-FleetFlex systems.
