We also realized that whenever we unplug the pressure switch from the Digital I/O, the relay LED corresponding to the PWM cable going to the spike turns off. That's normal, correct?

Yes, that's how it should be. When the DSC senses the pressure switch is open (ie, disconnected or over ~115psi), it turns the compressor relay off.
Basically, from what you're telling us, it seems like a PWM cable or spike problem at the moment. Try switching out the cable and/or spike with new ones until the light on the spike goes on.
