The Multiquip EM508578 is a genuine OEM Connector V30-4 designed for V304EH, V304ER, and V304EY walk-behind vibratory rollers. As a factory-sourced component, EM508578 matches the original connection geometry and terminal configuration specified for these machines at the time of manufacture. Sourcing a genuine OEM connector ensures the electrical circuit interfaces correctly with the roller's wiring harness, maintaining the integrity of the system it serves. DHS Equipment supplies this part direct, so you can confirm fitment and order with confidence.
Key Features
- Factory-Matched Electrical Interface — Genuine OEM construction ensures the correct terminal pitch, locking tab design, and contact material grade for this specific connector position on V30-4 series rollers.
- Direct-Fit Installation — Engineered to seat and lock into the existing harness receptacle without modification, preserving the original circuit routing on the V304 platform.
- Confirmed Roller Fitment — Verified for use on V304EH (electric-start Honda), V304ER (electric-start Robin/Subaru), and V304EY (electric-start Yanmar) walk-behind vibratory rollers.
- Electrical Circuit Integrity — A correctly seated connector maintains stable signal and power continuity; a damaged or mismatched connector can cause intermittent faults, failed starts, or loss of control functions on the roller.
- OEM Part Number Traceability — Part number EM508578 is the Multiquip-issued reference, making it straightforward to cross-check against your machine's parts manual before ordering.
A connector is an electrical joining component that links two sections of a wiring harness or connects a harness to a component such as a switch, sensor, or motor. On walk-behind vibratory rollers like the V304 series, connectors carry the low- and high-current signals that control engine starting, throttle, and compaction functions. When a connector corrodes, cracks, or loses its locking retention, the circuit becomes unreliable — producing symptoms that range from intermittent electrical faults to complete loss of a controlled function. Replacing a worn or damaged connector with the correct OEM part restores a clean, secure electrical junction and eliminates the source of those faults.
