  If this a potentiometer, or a Pot, as it is commonly referred to. Then follow these connections:
  
  1. The middle leg is the connection to the wiper or jockey of the potentiometer.
  
  2. The other two legs are for the supplies. Note supply does not necessarily mean a power source. It could be any two points in a circuit with a potential difference.
