I'm having problems with the compressor as well. I have the coding down, however I am not sure if the pwms are connected in the right direction. Is the ground (the black cable, for a regular white,red,black pwm) suppose to face in towards the sidecar or outtowards the edges? Also, I could not find the pin specs for the relay either, which pin is ground, +12, etc.?

EDIT:
okay I'm not sure whats wrong with ours. The compressor is functional, we have tested it with the battery. The relay is plugged into the relay port 1, and the pressure switch is on digital IO 1, both of the ground pins are facing out.
For the code,
I initialize the compressor using Compressor *m_com; at the beginning of the class, and declare it in the constructor: m_com = new Compressor(1,1); I do m_com->Start(); on the next line. This should start the compressor correct? It shows no activity for some reason.
