Howdy. Here for quian/maxfine mxf150-4n

[Rix86]

I'm Rick. I live in tacoma washington.
Just got a china bike. Maxfine mxf150-4n.
I'll get a pic after work today.
The main wire harness is super duper butchered. I was wondering if there's a manual somewhere I can buy or download, and if there's parts somewhere I can buy, or a comparable model (that it's a copy of?) that I can use parts from.
Or Am I supposed to ask elsewhere?

Any help is appreciated.
