I just bought an engine from what was supposed to be off of a 2014 klx250s and I can’t find the wiring diagrams that match my connectors coming off of the engine and what they do. Only one I’m sure of is the connector with 6 pins would be for the reg/rectifier. Any help is appreciated!! And just for clarification I’m putting this on a go kart so I only need the bare minimum to run it no accesories

 

1. 3/5 pictures don't have the wire colors.
2. You don't know what year engine you have, nor wiring diagram you have.
3. You havent' identified any wiring coming out of your engine.
The BL/Y is probably your starter. I think I'm done here, good luck.
