Complete Wiring Harness Kit for Chinese 4-Stroke Vertical Engine ATVs – Everything You Need in One Box
Is your ATV stuck in the garage because it won’t start? Or perhaps you’re looking to overhaul the entire electrical system without the headache of sourcing individual parts that might not be compatible? This complete wiring harness kit for Chinese 4-stroke vertical engine ATVs is the perfect solution. Get everything you need in one single order, ready for installation.
Note: Exclusively compatible with Chinese ATVs equipped with a 4-stroke vertical engine and electric start, ranging from 150cc to 300cc. Not compatible with GY6 (horizontal) engines or mini ATVs (49cc–125cc). Please verify the plug shapes, pin counts, and component configurations against your original parts before purchasing.
Why choose this electrical kit? (Key Benefits):
- All-in-one electrical system — 9 essential components included, eliminating the risk of compatibility issues between parts from different suppliers.
- Versatile compatibility — Designed for 150cc, 200cc, 250cc, and 300cc engines, covering the most common Chinese vertical engine configurations.
- Synchronised CDI and Stator — Supplied as a matched set to prevent ignition issues caused by mismatched components.
- Voltage Regulator/Rectifier included — Protects your battery from voltage spikes, significantly extending the lifespan of your electrical system.
- Ignition switch with 2 keys — Replace your entire starting system in one go.
- Vertical engine-specific plugs — Designed for direct connection in most cases, minimising the need for cutting or modifying your existing wiring.
Details and Performance
The wiring harness is constructed with high-quality insulation designed to withstand the vibrations and high temperatures typical of off-road use. The 4-stroke CDI ensures precise ignition timing across the entire rev range, while the stator/magneto is engineered to provide consistent power for 150cc to 300cc engines.
The solenoid relay protects your circuits from the high current draw of the starter motor, and the voltage regulator efficiently converts the stator’s AC output into stable DC power. The included ignition coil and spark plug ensure a strong, consistent spark, while the handlebar switch block centralises control of your headlights, horn, and indicators.

Frequently Asked Questions
Is this compatible with the GY6 engine?
No. GY6 engines are horizontal and feature a completely different electrical configuration and plug layout. This kit is designed exclusively for 150cc–300cc 4-stroke vertical engines with electric start.
Will this work on a 125cc ATV?
It is not recommended. 49cc–125cc ATVs typically use horizontal GY6-style engines or different electrical setups that are incompatible with this kit.
How do I check compatibility with my ATV?
Compare the shape, pin count, and position of the plugs on your original components with those shown in the product images. If your engine is a 4-stroke vertical type with electric start and falls within the 150cc–300cc range, this kit is highly likely to be compatible.
Do I need to modify the wiring to install it?
Generally, no — the plugs are designed for standard Chinese 4-stroke vertical engines. However, due to variations between manufacturers, minor adaptations may occasionally be required. We recommend verifying your connections before final installation.
Are the battery and starter motor included?
No. The kit contains only the components listed in the ‘Package Contents’ section. The battery and starter motor must be purchased separately if required.
