SHIQINHA Complete Wiring Harness Kit for 50–125cc ATVs — TaoTao/Coolster Compatible, Includes CDI Coil Regulator & Starter Relay

If your quad's electrical system is unreliable or piecemeal, this all-in-one wiring harness kit provides a single, organized solution. It groups the ignition coil, stator, CDI, starter relay/solenoid, voltage regulator, keyswitch and a multi-function handlebar switch into a matched assembly compatible with many TaoTao, Coolster and similar Chinese-brand ATVs. The kit is designed to simplify installation, reduce troubleshooting time and replace worn or scattered electrical parts with a coordinated harness.

Will this wiring harness fit my ATV model?

Compatibility covers a broad range of 50cc–125cc Chinese 4-stroke quads, but it is not universal. Check the included magneto/stator photo and connector shapes against your machine before ordering to ensure proper fit.

• Fits many TaoTao and Coolster 50cc–125cc models (examples include ATA-125D, ATA-110 series, 3050/3125 variants).
• Also compatible with brands like Kazuma, Baja, Roketa, Sunl, Buyang, Icebear, Loncin, Lifan, Redcat, Vitacci, Coleman and similar.
• Not compatible with GY6-style motorbikes or 200cc–250cc Zongshen/Lifan stator/CDI systems.

What components are included and how do they improve the electrical system?

The kit includes every primary electrical component required for a typical 50cc–125cc ATV replacement. By supplying matched parts, it reduces wire splicing and unreliable connections common in piecemeal repairs.

• 1 x complete 110cc ATV wire harness with labeled connectors for clean routing.
• 1 x ignition coil, 1 x 5-pin AC CDI box, and 1 x 6-coil stator to restore ignition and charging.
• 1 x starter solenoid/relay, 1 x spark plug and 1 x keyswitch for dependable starting.
• 1 x 4-pin full-wave regulator/rectifier, 1 x upgraded multi-function ATV switch, fuse and cable ties for secure installation.

How difficult is installation and what should I check before I start?

Installation is straightforward for anyone comfortable with basic ATV electrical work, but verification steps reduce the chance of incompatibility. Use the photos and connector layouts to match your vehicle before proceeding.

• Visually compare the stator/magneto and CDI connectors shown in product photos to your quad.
• Disconnect battery and follow color-coded wires and labeled plugs for easier routing.
• Secure harness with included cable ties and replace fuses as needed to protect the system.

What limitations or common pitfalls should I be aware of?

The kit is engineered for many common Chinese ATV platforms but will fail if connectors or stator types differ. Buying without confirming the magneto shape or CDI pinout is the most frequent cause of returns.

• Does not fit GY6 scooters or larger 200–250cc engines with different stator or CDI designs.
• Incorrect installation or mismatched stator/CDI will prevent the kit from functioning properly.
• Always compare the provided images to your existing parts before purchase.

Who is this for: This SHIQINHA harness kit is intended for DIY mechanics, small repair shops and ATV owners who need a consolidated electrical replacement for 50cc–125cc Chinese 4-stroke quads. It suits anyone replacing multiple failing components or converting scattered wiring into a single, serviceable assembly — provided their model matches the kit's stator and connector layout.
