Complete ATV Wiring Harness 50cc-125cc – A hassle-free solution for damaged wires and burnt connectors
Is your ATV failing to start, suffering from faulty lights, or plagued by a mess of improvised wiring? This is a common issue with older Chinese-manufactured ATVs. A complete wiring harness replacement solves these electrical gremlins once and for all—replacing the entire system rather than just a single wire or connector.
Note: Before ordering, please check your connector types and pin configuration. While this harness is compatible with most Chinese-built 50cc, 70cc, 90cc, 107cc, 110cc, and 125cc ATVs, minor variations between manufacturers can occur.
Why choose this wiring harness? (Key Benefits):
- Complete System Coverage — Includes connections for the CDI, magneto, voltage regulator, starter solenoid, ignition switch, and front/rear light clusters in one package.
- Broad Compatibility — Designed for 50cc, 70cc, 90cc, 107cc, 110cc, and 125cc engines, including both horizontal and vertical configurations.
- Plug-and-Play Installation — Features standardized connectors to match Chinese manufacturing specifications, meaning no cutting, splicing, or complex modifications required.
- Built for Off-Road Use — High-quality copper wiring with durable PVC insulation, engineered to withstand engine heat, moisture, and vibrations.
- Cost-Effective Repair — Replacing the entire loom is often cheaper and more reliable than paying for hours of diagnostic labour to fix an aging electrical system.

Frequently Asked Questions
Is this compatible with my 110cc Chinese ATV?
Yes. This harness covers the entire 50cc–125cc range, including 110cc models. However, we recommend comparing your existing connectors against the product photos, as minor variations can exist between different manufacturers.
Can I install this myself without electrical experience?
The connectors are colour-coded and shaped for easy identification. If you have a basic wiring diagram for your model and a bit of patience, it is a manageable task. If you are unsure, a professional mechanic can typically install this in under 30 minutes, saving you hours of troubleshooting.
Is the starter solenoid included in the package?
No. The package includes the complete wiring harness with the necessary plug and circuit for the solenoid, but the physical starter solenoid unit is not included. If you require a new solenoid, it can be purchased separately.
Does it work on vertical engines as well as horizontal?
Yes, this harness is fully compatible with both horizontal and vertical engine configurations commonly found in this range of Chinese ATVs.
