The Multiquip 22318 Engine Harness is a genuine OEM Engine Harness designed for the STXD6i and HTXD6i hydrostatic ride-on power trowels. As a factory-sourced component, part 22318 is manufactured to the same specification as the original, ensuring correct connector placement, wire gauge, and routing for a direct installation. This harness is confirmed to fit the STXD6i and HTXD6i Whiteman ride-on trowel models, giving you confidence that you are ordering the right part for your machine.
Key Features
- Genuine OEM Electrical Integrity — Factory-sourced wiring with correct wire gauges, insulation ratings, and connector terminals matched to the original harness specification.
- Direct-Fit Installation — All connectors, lengths, and routing points correspond to the original harness layout, so the harness drops in without cutting, splicing, or re-pinning.
- Confirmed Trowel Fitment — Verified compatible with STXD6i and HTXD6i hydrostatic ride-on power trowel models.
- Full Engine Circuit Coverage — Maintains clean, uninterrupted electrical signals between the engine and machine controls, supporting consistent throttle response, ignition, and sensor communication.
- Electrical Safety Compliance — A properly functioning OEM harness protects against shorts, ground faults, and erratic control behavior that a damaged or incorrect harness can introduce in high-vibration trowel applications.
The engine harness is the primary wiring assembly that connects the engine's electrical components — including the ignition system, throttle position sensor, and safety switches — to the machine's control circuits. On hydrostatic ride-on trowels like the STXD6i and HTXD6i, reliable electrical communication between the engine and the hydraulic control system is critical for consistent blade pitch adjustment and drive response. A damaged, corroded, or incorrect harness can cause intermittent shutdowns, loss of throttle control, or failure of safety interlock circuits, making timely replacement essential for safe and predictable operation.
