Evo IX USDM fail safe (Mac valve) diagram?

[dsm1gb]

I'm trying to figure out how to wire my mac valve for fail safe with a MBC on my evo IX (USDM)

I cant find a diagram, this is my last step so any help would be greatly appreciated.

I think this one should work.

So I have my Mac valve connected to a constant 12volt source, the same as my boost gauge, wideband etc, Is this correct to have power to it at all times?

It would be much better if you can connect the mac valve to a switched 12V, active only at the "pre-crank" or "run" ignition key position.
