Is that " 2 pairs of power wires joined at the drive" mean 2 pairs connected together?
Implying there is just one pair of supply conductors needed?
What is the motor technology?
DC? BLDC? etc.
not sure how to word that
i have a mill i am retrofitting and cant recall which wire color does what
there was a great picture in google but for the life of me i cant find it again!
there is 4 power wires and a yellow ground
on the machine it had the 2 pairs of power wires joined at the drive

4 power wires out of the brushed servo. 1 ground wire
i followed them to the board and at the terminal strip they were paired with lugs.
so i am assuming they have a basic + and - power requirement

There is no standard color code for that cable. You will need to ring out the wires or open the connector at the motor end.
Pins C/D is A1 and pins F/G is A2. Pin P is ground.
Now A1 and A2 may need to be swapped as pairs to get rotation direction right.
excellent
thanks i will give it a go.....

You can trace/identify continuity of each A1/A2 pairs from the MS3108 connector end.

A1 and A2, are these both just power wires to drive the servo or is one a field winding or some other magic?

These motors were PM field. Hence per label EXCIT(ation) - PERM Magnet.
