SHIQINHA Complete Wiring Harness Kit for 50–125cc Chinese ATVs — TaoTao/Coolster Compatible, Includes CDI, Stator, Regulator

SHIQINHA Complete Wiring Harness Kit is a full electrical replacement bundle designed to restore or upgrade 50cc–125cc Chinese 4-stroke ATVs, including ignition, charging, and starting components in one modular assembly.

If your TaoTao, Coolster, Kazuma or similar Chinese-built ATV has electrical trouble, this kit groups all the common high-failure parts into a single, plug-and-play wiring assembly. Instead of hunting down individual components across different suppliers — coil, CDI, stator, rectifier, solenoid and the ignition key switch — this package supplies matched parts and connectors to simplify installation and improve reliability.

Which ATVs and engine sizes does this wiring harness fit?

This harness targets most 50cc–125cc Chinese 4-stroke ATV models from popular makers such as TaoTao, Coolster, Baja, Kazuma and others. It was built to match the common connector layouts used on those small-displacement quads, but it is not compatible with GY6 motorbikes or larger 200cc–250cc models that use different stators or CDI units.

• Compatible with TaoTao models (ATA-110/125 series) and many Coolster 110/125 variants.
• Also fits brands like Roketa, SUNL, Loncin, Lifan, Zongshen, Vitacci and similar Chinese quads.
• Not suitable for GY6 scooters or 200–250cc Zongshen/Lifan ATVs with different magnetos.
• Always compare the included stator photo to your existing unit before ordering.

What components are included and how do they improve function?

The SHIQINHA kit arrives as a complete assembly: a multi-connector wiring harness plus the key electrical components commonly replaced together. By delivering matched parts, it reduces mismatched connections and eliminates the need for cross-referencing multiple part numbers.

• Complete wiring harness with integrated sub-assemblies for simplified routing.
• Includes ignition coil, 5-pin AC CDI, 6-coil stator, starter solenoid, spark plug and ignition key switch.
• Full-wave 4-pin voltage regulator/rectifier to stabilize charging output.
• Supplies fuse, cable ties and a 3-function kill switch for tidy installation and basic protection.

How difficult is installation and what should I check first?

Installation difficulty is moderate: basic wiring and mechanical skills are required, plus common hand tools. For best results, disconnect the battery, document original wire routing, and compare the kit’s connectors and stator shape to your quad before connecting anything.

• Verify stator mounting hole spacing and plug shapes against your machine.
• Label original wires if needed and route the harness along factory paths using the included cable ties.
• Test charging and ignition circuits with a multimeter after fitting but before final reassembly.
• If unsure, consult a technician familiar with small Chinese ATVs to avoid installation error.

What limitations or compatibility warnings should I be aware of?

The kit covers a wide range of 4-stroke small ATVs but is not universal; mismatched stators or non-standard CDIs will prevent proper operation. This product is a replacement harness for typical Chinese quads and is not designed for motorcycles that use different electrical platforms.

• Not compatible with GY6-style scooters or 200–250cc ATVs using different magneto/stator designs.
• Incorrect stator or wrong CDI will cause charging or ignition failure if installed without verification.
• Always inspect photos and match connector counts and shapes before purchase.
• Do not assume fitment by displacement alone; check model specifics and mounting patterns.

Who is this for: This SHIQINHA wiring harness kit is aimed at ATV owners, mechanics and restoration hobbyists working on 50cc–125cc Chinese-built four-stroke quads who want a one-stop electrical replacement. It suits anyone replacing multiple failing components at once or upgrading to a coordinated set of ignition and charging parts to reduce troubleshooting time. If you need precise compatibility confirmation, compare the kit’s stator and connector photos to your ATV before ordering.
