Vacuum routing help on SD setup

I have a brand new motor that I am putting together. Its a 350 with a miniram intake and I'm running a speed density setup. I have 3 vacuum ports on my miniram I can use, 2 on the pass side and one on the back of the intake. There are also 2 ports on the passenger side of my throttle body which I'm not sure if they are vacuum ports or not.

These are the vacuum lines I know I need to run: Heater source, Map sensor, fuel pressure regulator, brake booster, vacuum ball that sits under the driver side battery tray.

On my valve covers I have a PCV valve in one and a breather in the other where does the PCV valve connect to?

The charcoal canister I also don't know how that hooks up and if indeed it needs a vacuum source.

So with what I have can somebody help me figure out how these things should be hooked up and where I should run everything. This is one of the last things to do before I can bring this motor to life.

Thanks

You have to run a big vac line on intake to brake booster, small line to MAP sensor, small line to FP regulator, medium line to PCV valve. Then run pass valve cover vent to TB, then TB to purge canister,

Then you can run the little hard line coming out of firewall straight to the underside of throttle body on bottom.

That "should" take care of everything.

Thanks for the reply. I'm not sure as to how the PCV and Charcoal canister hookup to the throttle body. I also have two more things that need vacuum, the heater source and the vacuum ball under the driver side battery tray.

So my 2 questions are how exactly do you hook up the PCV and charcoal canister to the throttle body.

and I don't seem to have enough vacuum ports for everything.

Also if somebody could post a stock vacuum hose routing diagram for a speed density setup, I would really appreciate that.

Thanks again

On that note. I just bought the pcv for my density setup. Anyone here know if the ccv is just an open valve (no restrictions unlike a one way a pcv). I just want to be certain
