Yamaha PW-SE mid-drive motor tear down

I have dismantled a Yamaha PW-SE mid-drive motor and looked what's inside.

Hi,
I have a PW-X2 and am building my own SpeedBox. Do you know if there is 5v to power a micro controller in the wiring harness and what wire?
Not the light switch power as I want to use that to change modes.
thanks Eddie
