AC Idle up with 12v pressure switch?

Post by lagos »

I need to setup AC idle up on my DIYPNP. As I understand it, I can run a wire directly from my pressure switch to input 1(IN), then Input 1(OUT) to Flex. However my pressure switch is a 12v switch and not a ground switch. Will this setup still work by just changing the input polarity in the software setting, or is there any other wiring need for a 12v switch?

You can run a 12V switch through the nitrous input circuit instead - this inverts it and brings it down to 5V.
