Re: Air Compressor Wireing question
Yes, you must use a spike relay to control the compressor via the pressure switch.

The default code from IFI has the pressure switch wired to Digital I/O 18, and the compressor on/off to relay_8.

digital_io_18 = INPUT; /* Used for pneumatic pressure switch. */
relay8_fwd = !rc_dig_in18; /* Power pump only if pressure switch is off. */
