Centre pin will be the wiper  :-+

If you want increasing Vout (centre pin) moving in a clockwise direction, looking from the front, Vlow goes to the left pin, Vout ( with respect to the left pin, Vlow ) comes from the middle pin and Vhigh goes to the right pin


If you want decreasing Vout (centre pin) moving in a clockwise direction, looking from the front, Vhigh goes to the left pin, Vout ( with respect to the left pin. Vhigh ) comes from the middle pin and Vlow goes to the right pin
