Wire identification. hookup of Sanyo Super L servo? Help?

Howdy..

I have 3 Sanyo Servo super L motors, Rutex drives to run them.

Encoders on end, wires, Red, blue, black, white, shield

If it was american, the red and black would be logical choices for
power. Sometimes the japanese like blue, euro like white.. so?

Going onto a gantry table if I ever get all the parts and loose ends
together.
