Multiquip 23190 Wire Harness Engine Control - OEM Replacement Part for HHX Trowels

This wire harness connects the engine to the control system on HHX ride-on trowels, routing power and signals between the ignition, starter, relays, and operator controls. When this harness fails due to abrasion, corrosion, or connector damage, you'll experience intermittent starting issues, loss of throttle control, or complete electrical failure during operation.

The harness is constructed with 16 AWG wiring throughout with specific 10 AWG conductors for high-current circuits. It integrates multiple relay connections (terminals 85, 86, 87, 87a, and 30) and multi-pin connectors that interface with the engine's ignition system and the trowel's hydraulic controls. Color-coded wiring (yellow, red, orange, white) follows the factory wiring diagram to ensure proper installation and circuit identification during troubleshooting.

This harness is specifically engineered for the demanding environment of concrete finishing equipment, where vibration, hydraulic fluid exposure, and continuous operation require industrial-grade electrical components.

Compatible with the following Multiquip models:

• HHXD5
• HHXG5
