BOOTOP PIN Complete ATV Wiring Harness Kit for 49cc–125cc Chinese Engines

All-in-one wiring solution for your ride

The BOOTOP PIN Complete ATV Wiring Harness Kit delivers a full electrics package designed to power a wide range of Chinese-made engines from 49cc up to 125cc. This universal kit combines essential components into one cohesive assembly, streamlining replacement and helping you restore reliable electrical performance on your ATV, quad, dirt bike, or go-kart. Built for practicality and durability, it emphasizes clean routing and consistent power delivery, so you can focus on the ride rather than tinkering with individual parts.

With this kit, you gain a complete set of parts that typically wear out or become brittle over time. The assembly encompasses a wiring harness, CDI (5-pin AC), ignition coil with lead, spark plug, solenoid relay, rectifier (voltage regulator), stator (magneto generator), ignition switch (two keys, waterproof), and an upgraded multi-functional ATV switch. The red wire marks the positive pole and the black wire the negative pole, a simple reminder to help guide installation and reduce miswiring when you’re replacing or upgrading components.
