CAFEZAYO Wiring Harness Kit for GY6 150cc ATVs — Complete 9‑wire Kit with CDI, Stator & Starter Relay

CAFEZAYO's Complete Wiring Harness Kit is a full replacement electrical set for GY6 150cc 4-stroke ATVs and small engines, including regulator, CDI, ignition coil, starter relay and accessories for a one-package rebuild.

If your 150cc ATV, go-kart or utility quad is suffering from intermittent starting, dead charging, or damaged wiring, this CAFEZAYO kit supplies the major electrical parts needed to restore function without hunting for separate components. Designed for GY6 152QMI / 157QMJ-style 4-stroke engines, the package groups the harness, stator, coil, CDI, starter relay and switches so you can replace a worn or incomplete electrical system with matched parts.

What exactly is included in the CAFEZAYO 150cc wiring kit?

The kit bundles all primary electrical components commonly replaced together when repairing a GY6 150cc ATV or similar small engine. Every essential part required for ignition, starting and basic charging is provided to minimize compatibility guessing.

Which vehicles and engines is this kit compatible with?

This kit targets a broad set of 150cc ATVs and similar models that use the GY6 152QMI / 157QMJ electrical pattern. It’s made to fit many commonly sold Chinese and aftermarket ATVs and small utility vehicles, but it is not universal for all scooters or mopeds.

• Works with many Tao Tao, Coolster, Yamoto, KLX, Kazuma, Kymco, Baja, Roketa and similar 150cc ATVs
• Also fits certain Chongqing and aftermarket 125–150cc ATVs listed by sellers
• Not compatible with scooter/moped electrical layouts — check your engine model

How should I install the kit and avoid common wiring mistakes?

Careful pre-install review and following the wiring schematic are crucial. Pay special attention to the magneto/stator wire colors and the CDI pinout before connecting; reversing or misrouting wires can prevent starting or damage components.

• Compare the stator diagram to your engine before connecting
• Securely fasten the two stator mounting holes to ensure proper grounding and alignment
• Route the harness away from hot exhaust and moving parts to prevent chafe
• Test continuity and use a multimeter to confirm regulator/rectifier output before full reassembly

What durability and performance features does the kit provide?

Components in this set are built for everyday ATV use and designed to protect the electrical system from overload and wear. The included regulator/rectifier and starter relay help stabilize voltage and reduce stress on the battery and CDI unit.

• Reinforced wiring harness with labeled connectors for faster swaps
• High-efficiency ignition coil and 6-pin AC CDI to improve starting reliability
• Regulator and starter relay included to prevent overload and extend component life

Who is this for: This CAFEZAYO kit is intended for ATV owners, small-vehicle mechanics and DIY enthusiasts working on 150cc GY6-style engines who need a single, complete electrical rebuild package. It’s ideal for those restoring or repairing Tao Tao, Coolster, Kazuma and similar small ATVs who want matched parts in one shipment. Verify your engine model (152QMI/157QMJ) and that the unit is not a scooter/moped before purchasing.
