Need quick help with iacv vac line routing.

I have eliminated all my emissions crap and over 90% of unneeded crap in engine bay. Was taking something off and start make sure ran fine etc. But when got to vac lines just got in a hurry. I attached a picture of a port on the iacv. I need to know where it runs to. This does draw vacuum when running. All you stock guys where is this run to???

Nevermind, that's on the other side. Look top-down on the IAC valve, there's a metal vacuum line, 90 degree, turned up. Should line up almost exactly with the screw (near your pinky knuckle in the pic) holding the IAC motor in.

What did you do with them? :P
If I'm reading this diagram correctly, says it goes to the canister purge thing.

I eliminated alot of crap. What purge thing? I got it idling today with it unhooked. Soon as plug off it dies out slowly. Really need figure out by tomorrow dying to get into boost with the new cams.

Threw my canister back on. One port goes to fuel tank I have that hooked up. But there are other lines. The one off IACV goes where and what does the other port go to.

I see three lines coming out the top. The one to the side goes (?)
The bottom goes to the iacv. the top one goes to the throttle body, under the intake pipe

yeah, that ish is beyond me.
If i keep my car, I'm'a have to go with ms, and do map. That makes sense to me, not maf sizing and all.
Then again, if I keep my car, it gonna get gutted, and 3.4l built for it.
Somebody should buy my server...

Nistune makes Maf changing pretty simple.
