HOOTO Complete GY6 Wiring Harness Kit for 150cc–250cc ATVs, Go-Karts — Full Ignition & Charging Kit with 8-Pole Stator

HOOTO’s Complete Wiring Harness Kit is a full replacement wiring system engineered to install or upgrade electric-start GY6-style 150cc–250cc ATVs, go-karts, scooters and utility quads.

This kit bundles every major electrical component you’ll need to restore or modernize a Chinese-made upright-engine GY6 vehicle: a GY6 150cc wiring harness, 8-pole magneto stator, 6-pin CDI, rectifier/regulator, ignition coil, solenoid relay, spark plug, upgraded multi-function ATV switch and a waterproof ignition switch with two keys. Components are assembled from durable electronic materials and are intended to fit many common makes and models that share GY6 electrical architecture.

Will this wiring harness fit my ATV, scooter or go-kart?

Compatibility covers many Chinese-manufactured units with GY6 upright electric-start engines in the 150cc–250cc range. It is not designed for smaller 49cc–125cc mini ATVs or bikes that use different stators or CDI pinouts. Carefully compare your vehicle’s stator and connector styles to the photos before ordering.

• Fits many 150cc, 200cc and 250cc GY6 electric-start engines
• Compatible brands include Coolster, Kazuma, Pitpro, Xmoto and others
• Not compatible with 49cc–125cc mini ATVs or non-GY6 stator designs
• Check the 8-pole stator and connector shapes against your unit

What parts come in the complete HOOTO wiring kit?

The kit supplies all primary ignition and charging parts plus switches and a spark plug so you can replace an entire wiring system in one purchase. Each item is selected to match typical GY6 wiring configurations and reduce cross-compatibility issues.

• GY6 150cc wiring harness with multiple routed connectors
• 8-pole 5-wire magneto stator with two mounting holes
• 6-pin CDI box, ignition coil, solenoid relay and rectifier/regulator
• Waterproof ignition switch with two keys, upgraded ATV switch, and spark plug

How do I install the harness and what should I consider?

Installation requires moderate electrical experience and basic hand tools; no printed manual is included so professional installation is recommended if you aren’t comfortable with wiring. Match connectors, secure grounds, and verify charging output before reassembly.

• Professional installation recommended for safety and reliability
• Verify stator polarity and CDI pinout match your engine before wiring
• Secure all connectors, fuses, and grounds; protect exposed terminals
• Test charging system and ignition timing after install

What materials and quality features does the kit offer?

HOOTO uses durable electronic materials to improve longevity under vibration and outdoor conditions common to powersports. The ignition switch is waterproof and the harness includes common protective sleeving; components are sourced to align with aftermarket powersports standards.

• Durable wiring sheathing to resist abrasion and heat
• Waterproof ignition switch with two keys for security
• Standardized connectors to simplify replacements
• Includes both charging and ignition components for a full-system swap

Who is this for? The HOOTO Complete Wiring Harness Kit is best suited to owners, mechanics and restoration shops working on Chinese-made GY6-style ATVs, scooters, go-karts and utility quads in the 150cc–250cc range who need a one-package electrical rebuild. It’s ideal when existing wiring is damaged, corroded or when you want to consolidate multiple aging components into a single upgraded set. If your vehicle uses a different stator, CDI format or is a smaller-displacement mini ATV, choose a kit specifically matching that model instead.
