EOPOAYI Complete GY6 Wiring Harness Kit for 150cc ATV/Scooter — Full Replacement with 6-Pin CDI & Regulator

EOPOAYI Complete Wiring Harness Kit is a full replacement electrical system built to restore and upgrade GY6 125–250cc 4-stroke engines, including TaoTao and Coolster 150cc ATVs.

This all-in-one wiring harness package supplies the core electrical components needed for GY6-style small engines: a pre-assembled harness, magneto stator, 6-pin CDI, ignition coil, starter solenoid, regulator/rectifier, keyed starter switch, multi-function ATV switch, spark plug, and cable ties. Designed as a budget-friendly repair or rebuild solution, the kit groups compatible parts so you can replace a damaged harness or build a reliable electrical base for a swap project without sourcing individual items.

What exactly is included and why does it save time?

The kit combines most of the parts you would replace when doing a comprehensive electrical refresh on a GY6-based vehicle. Buying a complete set eliminates repeated orders and compatibility guessing, letting you install everything in one shop session.

• Complete GY6 125/150 wiring harness for multiple engine variants
• 8-pole magneto stator (5-wire) and 6-pin CDI ignition box
• Ignition coil, starter relay solenoid, voltage regulator/rectifier
• Keyed starter switch with two keys, upgrade 10-wire 5-function ATV switch
• A7TJC spark plug and 10 zip ties for tidy routing

How durable and safe are the components under real-world use?

Parts are built from reinforced materials and subjected to verification steps intended to reduce failure rates under normal riding conditions. The harness and electrical devices are designed to limit overload risk and help protect against shorts, extending service life compared with worn stock wiring.

• Heat-resistant connectors and insulated wiring to resist abrasion
• Regulator/rectifier included to manage charging voltage and protect battery
• Starter solenoid and proper grounding points reduce strain on switches
• Supplied zip ties make secure mounting and neat routing easier

Will this kit fit my vehicle and how do I confirm compatibility?

The harness targets GY6-style 4-stroke engines commonly used in Chinese-made ATVs, scooters, and UTVs. Verify fit by comparing your magneto stator pattern, pin counts, and connector types to the kit’s components before purchasing.

• Compatible with GY6 125/150/200/250 and 152QMI/157QMJ engines
• Fits brands like TaoTao, Coolster, Baja, Roketa, Kazuma and similar models
• Check the stator’s 8-pole, 5-wire layout and the CDI’s 6-pin connector
• Refer to your vehicle wiring diagram for matching color codes and pins

How should I prepare for installation and what tools will I need?

Before installation, inspect the wiring diagram—especially the magneto/stator connections—and gather basic tools. Having wire crimpers, dielectric grease, a multimeter, and mounting hardware will speed the job and improve reliability.

• Confirm wire routing and grounding points prior to connecting components
• Use a multimeter to test continuity and correct pin assignments
• Apply dielectric grease to exposed connectors to reduce corrosion
• Secure wires with supplied zip ties for vibration resistance

Who is this for: This EOPOAYI kit is intended for DIY mechanics, small-shop technicians, and hobbyists rebuilding or repairing GY6-based ATVs, scooters, and UTVs who want a single, cost-effective package of proven electrical parts. It suits owners replacing a failing harness, prepping a donor engine for installation, or upgrading multiple wear-prone components at once. Always double-check your vehicle’s wiring diagram and connector types before ordering to ensure a direct fit.
