RE: How to hook up my ESC to my brushless motor?
None of the wires on a brushless motor are "positive" or "negative." That concept does not apply to brushless motors.
I have brushless motors that came with no wires at all. I have others whose wires are all the same color. I have one whose wire colors are yellow, blue, and green!
The colors of the motor wires on a brushless motors simply have no significance.
