Regardless of what that guy from FBI said in your other thread, I would never run one compressor on 14 gallons unless it was an engine driven compressor or Oasis. 5 gallons is the max for about any viair compressor, 9 is the max for an AZ, and about that compressor that FBI has.... well... i'd search around first and see the horror stories that people have had when going to FBI for parts before I buy anything from them.
As for connecting it all up... you need airline and fittings for the air parts, and electrical connectors and wire for the electric stuff.
If you haven't already, go spend a few hours and read around
