This will be the most frustrating install you do
Does it work... yah.... did it take 3 different complete sets to get one complete working set yes.... If your buying this for switch control don't, In all 3 sets i ordered NONE of handlebar switches worked and infact 1 shorted out nearly causing a fire. The only reason i am giving this any starts is that it comes with everything and its dirt cheap... but like others have said your going to get what you pay for. If i did it again i would have bought something else. There are zero instructions so you will need to refer back to this website... you will absolute need to have trouble shooting skills to install this and get everything working correctly.

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.

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.

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

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.
