pulled up an old schematic and if memory serves me well, red is power on all the time, black ground, yellow and white are in and out signal wires, test it out your self to see which is which, my guess is on the 3 wire system, yellow and white carried the motor current and just drove the motor to the limit switch, the 4 wire does the same, but there is only signal current on the yellow and white instead of motor current which is carried on the red and the relay in the actuator, so the switch lasts longer. So just put power on the red and the switch to yellow & white. If you still have the old dead one and feel like sending it to me, I'll rebuild it with FETs and send it back to you for a spare for far less that the new, probably just postage and parts, I do it something to do. PM me if you want.
