Once the two pairs have been identified, hooked them up to a
controller. Send the motor a control sequence activating each of the
coils. If the motor rotates, its hooked up correctly. If it doesn't
rotate correctly, reverse the end taps on one pair of the windings and
it should work properly. A full step (wave drive) sequence is probably
the easiest to use for testing.
