Identifying a Fiegao motor

I have a Fiego motor and though I was told it's a 9XL, I can't positively identify which one it is or how to wire it to an esc due to the lack of color coding on the wires. Is there a way to tell?

Can length is 58.65 mm.
Diameter of the fron of the can is 38.53 mm.
Shaft diameter is 5 mm.



Thanks in advance!
