You must use a multimeter on the continuity (beep) setting. Two wires will show a steady resistance (usually 20 to 100 ohms)—these are your motor power wires. The remaining three wires are the microswitch (Common, Normally Open, Normally Closed). Manually turning the valve will cause the continuity to flip between the microswitch wires.
