I just purchased this son. The ignition key is pulled out of the harness. Is there a good source for aftermarket replacement parts? I some online that are a generic 4 wire and I'm wondering if they would work. I have a dealer somewhat close but doesn't stock many parts and he told me he has nothing in stock for a 90.

 

Here one I found on ebay.
ATV Key Ignition Switch 4 Wire 50 70 90 110 125 150 200 250cc taotao Sunl I KS06 | eBay

 

You may have to use your existing connector and wiring colors may be different,but possible it can work. Worth a shot at 8 bucks versus 45 bucks for an oem switch.

 

I'm currently just twisting the wires together and it's working. Only issue is when he's done riding and forgets to disconnect the battery dies. I think I will try it and see what happens.

 

Awesome! That's probably way easier then what we went through to get our 7 year old

 

Between the ages of 16 and 20 I would have sold mine cheap..
