Complete Electrical Overhaul: GY6 150cc Sport Wire Harness

Eliminate electrical gremlins and “ghost” shorts with the Universal Parts Complete GY6 Wire Harness. Designed specifically for 125cc and 150cc 4-stroke “Sport Style” scooters, this “long-case” harness serves as the complete central nervous system for your vehicle. Unlike partial repair looms, this is a full-vehicle solution that runs from the headlight to the taillight, ensuring every component receives stable, reliable voltage.

Technical Performance Features

• Gauge & Switchgear Ready: Includes dedicated pigtails and pre-installed bulbs for your instrument cluster and handlebar switches, significantly reducing installation time.
• 5-Pin Regulator Plug: Features the standard 5-pin connector used by the most reliable GY6 charging systems, ensuring compatibility with high-output stators.
• Reinforced Loom Protection: Wrapped in high-temp electrical conduit to protect against vibration, engine heat, and moisture in the harsh environment of a scooter’s inner frame.

Mechanic’s Note: GY6 wiring can vary wildly by factory. Before installing, lay the new harness next to your old one and verify the **Regulator Plug (5-pin)** and the **Stator Connections** match your existing components. If your scooter has a “Retro” style body (like a Vespa clone), this “Sport” harness may be too long or use different headlight connectors.
