OTOHANS AUTOMOTIVE Stator Coil CDI Wiring Harness for 150cc-300cc 4-Stroke ATVs — Full Copper Wiring, Direct-Replace Kit

Complete replacement stator coil, CDI and full copper wiring harness engineered for 4-stroke Chinese-made ATVs and quads from 150cc to 300cc.

This OTOHANS AUTOMOTIVE kit bundles the stator coil, CDI unit and a full-copper wiring harness to restore charging, ignition and lighting functions on many 150cc–300cc 4-stroke ATVs, quads and dirt bikes. Designed for compatibility with popular Chinese engine brands such as Lifan, Loncin, Ducar, Shineray, Zongshen and YX, the assembly is a direct-replacement style that makes it easier to match your original components and wiring layout.

How do I know this harness fits my ATV?

Check the physical shape, connector types and number of wires against your original stator and CDI before purchasing. This kit targets the common 150–300cc 4-stroke Chinese engine patterns, but it does not fit GY6 or small-displacement minibike engines.

• Compare photos and plug layouts to your old parts.
• Confirm engine family (Lifan, Loncin, Zongshen, etc.).
• Not compatible with 49cc–125cc GY6-style engines.
• If unsure, consult a mechanic or send a part photo to the seller.

What components are included and what materials are used?

The package contains a stator coil assembly, CDI box and a full-length wiring harness assembled with full copper conductors for reliable conductivity. Connectors and insulation match OEM-style layouts to simplify replacement and reduce electrical resistance.

• Stator coil matched to common 4-stroke mounts and shapes.
• CDI ignition module pre-wired for direct splicing or connector use.
• Full-copper wiring for improved current flow and less heat.
• Insulated connectors and strain-relief sections to prevent chafing.

How should I install the kit safely?

Follow the included wiring and installation diagrams step by step, and reconnect only after verifying wire color and terminal positions. If you lack electrical experience, hire a qualified mechanic to avoid miswiring that could damage the harness or vehicle.

• Turn off the battery and remove the key before starting work.
• Match each connector and grounding point to the diagram.
• Test continuity and charging output with a multimeter before final assembly.
• Avoid forcing connectors; replace damaged terminals first.

What should I avoid and what warnings apply?

Do not attempt to install this harness on incompatible engines—especially GY6 or minibike stators—or with unknown wiring modifications. Incorrect installation can cause harness overheating or fire in rare cases, so proceed cautiously and double-check all connections.

• Not for 49cc–125cc minibikes with different stator/CDI designs.
• Do not mix with aftermarket parts that change pinouts without rewiring correctly.
• If wires show damage, repair or replace them before use.
• Seek professional help if wiring colors or connectors don’t match expected diagrams.

Who this is for: Riders, DIY mechanics and repair shops working on Chinese-made 150cc–300cc 4-stroke ATVs, quads and dirt bikes who need a direct-style electrical replacement to restore charging and ignition systems. Choose this OTOHANS AUTOMOTIVE kit if you want a full stator + CDI + copper harness solution that aligns with common OEM layouts—but confirm compatibility with your existing components or consult a mechanic before installation.
