There are several things related to the pressure switch that could keep the compressor from turning on that are not related to the Digital Sidecar or Relay. Is the pressure switch plugged into the port defined in your code? Is the pressure switch wired between signal and ground? Is the Digital Sidecar properly powered (are all 3 power LEDs brightly lit) if you remove the DB-37 cable?
