Aha! So my resistor needs to go to pin 1 AND 2?
Thanks

Yes. You can tie the resistor to just pin 1 and add a jumper to pin 2, or, twist pins 1 and 2 90deg and run the resistor lead through both and solder. But yes, pins 1 AND 2 are connected to the resistor.

basically you're doing two operations in one.

To make a potentiometer 'safer' as a variable resistor, you always tie the wiper to one of the pins that's not used, so that if the wiper fails, the resistor becomes a max resistance of the pot, to ensure 'some' resistance is always there. The fact that you're connecting a lead for a resistor to it means you can just use the resistor's lead to join the first and second pins of the pot together. You could also waste some wire and just jumper the 1 and 2 with that and then just connect the resistor into pin1, but why?
