Good fit and fixed the problem - good quality
Worked like a charm and the 4 wheeler is back in operation. Good quality and after several months no issues to report. I would recommend this kit.

Perfect for 110cc tao tao and like model from 49cc and up!! Easy install almost plug and play on all models but straight forward enough.

Cheap Quality and Bad not working parts
I was using this to replace the harness on a small kids Chinese ATV 110. The stator fit fine, but the pulse coil lead was about 1/4" short. When mounted it was really pulling on the lead. The overall harness is very cheap and about 4" to short in a few places. The original harness had heavier gauge wire of much better quality. The ignition switch was defective, it would turn the power off and on ,but the engine kill in the off position was not working. I had to open the ignition switch and found a bent contact for the kill switch. Repaired the bend in the contact and it worked. I checked every wire before connecting it to make sure I was not going to short anything out. Many wires were connected incorrectly in the harness that needed to be fixed. I had to take all the tape and loom off the harness to trace all wires. This harness does not come with the starter wire that goes from the starter to the starter Relay/Solenoid. The handlebar switch was wired incorrectly at the plug. I had to remove the pins in the plug to match up the pins of their harness. I would not recommend this kit.

Not model specific
I made it work for my Pentora 125 kids atv. They are all pretty similar but they aren’t model specific my four wheeler starts up, headlights work, brake light works. But my neutral and reverse light don’t work because there’s no specific wire for it. I’m just glad I was able to make it work enough to ride.

Decent
Good price, works as it should, fit fine, good quality, easy install but you might need to re-pin some wires to the correct locations on connectors & splicing wires depending on your model of Chinese atv

New ATV Electronics
Complete wiring set with all major electronics. Easy install, but didn’t include a wiring diagram, which required some extra time searching internet that matched this harness.

Got the bike working, very cheap parts
Many of the wiring colors do not match. No documentation beyond the picture in the product listing. The spark plug connector came apart from the ignition coil after less than 2 months. With a bit of trial and error I got the harness to work but now that the spark plug cable doesnt work i have to buy another. No way to contact for support.

Works great! Used it to replace an old harness, For a 110cc atv. Follow the instructions in the pictures and verify all your connectins. Once I had everything installed I was getting no power to engage the starter. The issue I had was the wiring for the brake switch at the front of the harness. The atv that I have does not have a male electrical receptacle from the brake system so I had an unused conection from the harness. I thought this might be the problem and I was correct. I had to make a jumper to complete the electrical connect and the starter fired. My assumption is this is a safety feature to have a brake switch engaged to be able to provide power to the starter.
