HOOTO Complete Wiring Harness Kit for GY6 150cc–250cc ATVs | Full ignition, charging & starter loom

HOOTO Complete Wiring Harness Kit is a full replacement electrical package designed to equip GY6-style 150cc–250cc ATVs, scooters, quads and go-karts with ignition, charging and switching components in one set.

This kit bundles the core electrical parts riders most often need when repairing or upgrading a Chinese-made upright GY6 engine vehicle. Rather than sourcing individual components, you receive a matched stator, CDI, ignition coil, rectifier, switches, solenoid and the main wiring loom configured for electric-start small-displacement powersports. The set is built for common 150cc, 200cc and 250cc GY6 variants but is not universal—verify the stator shape and connector layout against your machine before ordering.

How does this kit restore my vehicle’s electrical system?

The HOOTO kit replaces damaged or missing electrical elements with parts sized and wired to work together. It supplies charging, ignition and starter relay functions so the engine can spark, charge the battery and use the electric-start system when relevant. Installing the harness reconnects lighting, switches and safety circuits back to a functional state.

• Includes a matching 8-pole magneto stator to rebuild the charging system.
• Comes with a 6-pin CDI box and ignition coil for consistent spark delivery.
• Supplies a rectifier/regulator to stabilize charging voltage for the battery.
• Provides a full main loom, ignition switch, starter solenoid and multifunction ATV switch.

What models and engines will this harness fit?

This wiring package is targeted at many Chinese-made electric-start upright GY6 engines in the 150cc–250cc range. It commonly fits ATVs, scooters, quads, go-karts and buggies built around those engine families. Compatibility can vary by year and manufacturer due to connector shapes and stator hole patterns, so inspecting the provided stator image against your unit is essential.

• Designed for GY6-style 150cc, 200cc and 250cc electric-start engines.
• Often compatible with brands like Coolster, Kazuma, Xmoto, and others.
• Not compatible with small-displacement 49cc–125cc GY6 variants with different stators.
• Check stator mounting holes and wire connectors before purchase.

What components are included and how durable are they?

The kit is a comprehensive collection of electronic and switchgear parts intended to be a long-lasting replacement. The wiring is insulated for vehicle use and the electronic modules are standard aftermarket designs used across many powersports repairs. While the set contains quality materials suitable for typical off-road conditions, professional installation is recommended to ensure longevity and safety.

• Package contains stator (8-pole, 5-wire), 6-pin CDI, ignition coil and spark plug.
• Also includes rectifier/regulator, starter solenoid, ignition switch with two keys and a multifunction ATV switch.
• Wiring harness manufactured from durable insulated cable and connectors.
• No printed installation guide included—professional fitment advised.

What should I check before buying to avoid fitment problems?

Because many small engines use similar but not identical components, match the visible parts to your machine before ordering. The stator mounting, plug types and CDI pin count are common mismatch points. Comparing photos and connector shapes will prevent returns and downtime.

• Compare the stator’s 8-pole pattern and fixing hole spacing to your motor.
• Confirm the CDI is a 6-pin type and connectors align with your harness ends.
• Ensure your vehicle uses an electric-start GY6 upright engine in the 150–250cc range.
• Do not use for 49cc–125cc or motorcycles with differing stator/CDI designs.

Who this is for: This HOOTO Complete Wiring Harness Kit is aimed at DIY mechanics, small workshop owners and powersports enthusiasts who need a single-source electrical rebuild for many Chinese-made GY6 150cc–250cc machines. If you own an ATV, quad, scooter or go-kart with the matching stator and connectors and want a consolidated set of ignition, charging and starter parts, this kit saves time compared with sourcing each component separately. If you’re unsure about fitment or lack wiring experience, consider a professional installer to complete the job safely.
