Volume Control for Diode Selection

How do I wire up an audio taper pot for a diode selection mod? I know a resistor needs to be in the mix, but I'm not sure how the pot's lugs are wired to the switch/dip switch and then to the board. What value of resistor would be a good starting point?

Also open to using a trim pot as well.
