The stator doen't know the difference......you are moving the sensor also....A-phase is always (v3) to the left of the sensor plug, B-phase center, C-phase to the right. You can also move the other end if you happen to strip out the "to-chassis" mount holes.
I set-up mine so the motor turn label is easiest for tech to see, over, under, thru the chassis. And make the sensor plug easiest to adjust (reach) while in the chassis.
