+Using a ohmmeter, with one terminal of the ohmmeter on one lead of the stepper motor, another terminal of the ohmmeter on another lead of the stepper motor, measure the resistance between all pairs of wires. Then, when you find a wire that will cause the resistance between pairs of wires to read about a half of a resistance between other pairs of wires, you've found the central tap wire.
