Wire schematic needed for E-scooter

I have been task to repair a small E scooter, all the wires have been disconnected from the controller and also all the body wires. I need a schematic of the whole scooter which I have been searching for days and have not found. I believe it is a China scooter and there are many variants of this scooter including E-scooter, Scoot-N-Go, Sunl and a few more, they are all the same. I have seen the schematic of the controller but no body wiring. I sure would appreciate any help on this subject.
