The Tohatsu 30 foot Main Harness Extension 3ZG761140M is a genuine 30-foot wiring harness engineered specifically for remote control installations on MFS 9.8hp through MFS 140hp four-stroke outboards. This extended-length rigging component provides the electrical connection between your engine and control system over substantial distances, enabling proper throttle control, gear shifting, and comprehensive engine monitoring on larger vessels.

Built to Tohatsu’s marine-grade specifications, this harness withstands the demanding conditions of saltwater environments while maintaining signal integrity across its full 30-foot length. This extended reach makes it ideal for large center console boats, dual console vessels, and any installation where the helm is positioned far from the engine mounting location. The generous length eliminates the need for splicing or extensions while ensuring clean, professional cable routing throughout the vessel.

Compatible with Tohatsu’s comprehensive four-stroke lineup including the MFS9.9, MFS15, MFS20, MFS25, MFS30, MFS40, MFS50, MFS60, MFS75, MFS90, MFS115, and MFS140 models, this harness integrates seamlessly with Tohatsu control boxes, key switch panels, and instrumentation systems. The design reflects Tohatsu’s commitment to reliable marine engineering with sealed connectors that resist corrosion and maintain consistent electrical performance over extended distances.

This genuine harness supports all critical electrical functions including tachometer signals, trim gauge operation, TOCS engine diagnostics, and emergency safety circuits. Northeast Marine stocks the complete range of Tohatsu rigging components to support proper installation across all vessel sizes and configurations.
