If you are using a pressure switch then this is correct.. If you are using a toggle switch to turn them on/off when you want, just use it in place of the Pressure Switch. Here's the diagram for 2 compressors/2 relays.
Let me know if that doesnt help you completely, Ill be on AIM all day if thats quicker. Good luck
