Valve Setup

[IvelDesigns]

I did a bit of thinking tonight, and decided i'm not gonna wait to do add a compressor, tank and valves to my bag setup. I started looking around on suicidedoors and found the tank i want (Stainless Steel 5 Gallon) and the compressor (Viair 460 150 PSI). But then i got to thinking about the valves and wiring. I'm not really sure what i need.

So can anyone help give me a list of items to get? How many relays do i need? just one for the compressor, or do i need one for each valve?

I am using slam specialties RE7's all the way around.
