Volume Pot Wiring Diagram

If you want the pot to turn in the opposite direction, pins 1 and 3 can be reversed. Be sure to always ground to the shell to avoid hum! I normally drill a hole inside the shell and attach a ring terminal with three ground wires - one to the element, one to the pot, and one to the connector.
