Please correct me if I'm wrong, I have our potentiometer connected this way and I'm about to connect it tomorrow. Please Please reply.
You ae correct: One "end" of the pot goes to black, the other "end" goes to red - this puts a 5 volt potential across the entire pot. You then connect the Wiper of the pot to the white, so the RC can read the voltage at the wiper contact (which varies from 0 to 5 volts). Using the diagram, black goes to 1 or 3, red goes to 3 or 1, and WHITE goes to TWO.
