Likewise. In my younger years it cost me a lot, and I don't mean just money.

I can relate

I've never been much into stereos so I'm not great when it comes to wiring. I used this for my switches/valves

Where would be an ideal place to run the 12 volt input from? I assume I want it somewhere where it's only powered when the ignition is on.

Also each one of the 8 valves has a ground wire, is ok to tie them together to the same ground or should I split them up? Is there a recommended distance where they should be grounded?
Sorry for the stupid questions

How many amps will the system draw? There are two auxiliary post on the fusebox that are switched on with ignition. I believe they are 30 amps each. Yes the grounds can be hooked together.

If I remember right it will be 20-30 amps

I recommend powering the relay direct but switched, not through the ignition. That way if your key switch or whatever goes bad you can still air the system up.
+1 on grounds ran together, and landing anywhere.
I have a master switch in the console.

Directly wired does sound better in that case, I’ve never done anything with bags so stuff like that is new to me.

Thus makes sense but could I get more specifics? This is how I was going to be wiring the compressors. Where would your master switch land, between the battery and fuse? Will any switch work or do I need one with specific amps?

Then the power that feeds the actual switches wired to the valves, would that get wired into the master kill switch as well?

Run it just like that, except instead of keyed power, use a switch. I am 99% sure that any switch will do, because you're interrupting the ground side of the relays so the amperage is low, but I'd like that confirmed by someone else.

Same here. I think I have that same diagram printed out from 20 years ago. But yeah, any old switch will do there.

No need, they can't run without a ground, and the master switch interrupts the ground.
