Hi PeterC,
I think the answer to your question is dependent on the Curtis Controller that you have. You will need to find its part or model number and specific operating manual with wiring diagram.
My project is using a Curtis 1238 controller that can use either the potentiometer or the 0-5V throttle. I have chosen to use a 2nd generation Prius throttle pedal which is self contained assembly to provide the 0-5V input.
