CAFEZAYO GY6 150cc Wiring Harness Kit — Complete 152QMI/157QMJ ATV Electrical Set with Regulator & CDI

This CAFEZAYO kit brings together every primary electrical part you need to restore or replace the wiring system on many 150cc GY6-style engines. Designed for ATVs and similar utility machines from brands such as Tao Tao, Coolster, Kazuma and more, the bundle pairs core components into a single purchase so you can avoid sourcing individual parts. Before installation, confirming vehicle compatibility and reviewing the magneto stator wiring diagram is essential because the kit is not suitable for scooter/moped models.

Which machines does this harness kit fit?

The kit is built to match a broad range of 150cc GY6-type ATVs and some 125cc variants. It lists compatibility with many common aftermarket ATV models and utility vehicles that share the 152QMI / 157QMJ engine family wiring layout.

• Common fit: Tao Tao, Coolster, Yamoto, KLX and Kazuma 150cc ATVs
• Also compatible with many Roketa, Kymco, Baja and Chongqing 150cc units
• Selected 125cc vehicles (see vehicle spec) and other GY6 150cc clones
• Not for scooter or moped electrical systems—verify engine/model match

What components are included and why they matter?

This kit consolidates primary ignition and starting components so you receive a ready-to-install set for most GY6 150cc applications. Each piece addresses a specific electrical function—charging, ignition timing, starting and on/off control—reducing troubleshooting time.

• Wiring harness: pre-terminated connectors to match OEM plug locations
• 8-pole magneto stator (5-wire): supplies charging and trigger signals
• 6-pin AC CDI box and ignition coil: handle spark timing and high-voltage output
• Starter relay solenoid, key starter switch with two keys and upgraded 9-wire ATV switch
• Spark plug included for a complete start-up package

How should I approach installation and avoid common errors?

Careful preparation prevents mismatches and wiring mistakes. Start by comparing the provided wiring schematic to your vehicle’s factory diagram, paying special attention to stator wire colors and connector pinouts.

• Compare the magneto stator diagram and confirm wire-to-pin assignments first
• Disconnect the battery (if present) and secure vehicle to prevent movement during work
• Match connectors visually—do not force non-matching plugs together
• Test electrical circuits with a multimeter before finalizing mounts and ties

What durability and performance features are built into the kit?

Parts in the CAFEZAYO harness kit are chosen for durability and service life in off-road and utility use. The kit pairs a voltage regulator/rectifier design and a starter relay to help control load and protect components from excess voltage or starter current draw.

• Durable wiring harness with insulated connectors designed for vibration resistance
• Voltage regulator function prevents charge-system overloads
• Upgraded 9-wire ATV switch and keyed start for added security and reliability
• Components preselected to match GY6 150cc electrical loads and spark requirements

Who is this for? This CAFEZAYO Complete Wiring Harness Kit is ideal for mechanics, hobbyists and owners of 150cc GY6-style ATVs or utility vehicles who need a full electrical replacement or a consolidated parts upgrade. If you own one of the listed models and are comfortable following wiring diagrams and basic electrical testing, this bundle provides the major pieces needed to get your engine charging, sparking and starting again. If you have a scooter/moped or an unmatched engine wiring layout, check vehicle specs before buying.
