5) Now the throttlebody...on the right side where according to the diagram above the primary and secondary imjector air bleeds connect and the oil injector air bleed. There are 2 small nipples and one big one. Which is which? Remember I removed the oil injectors.

As you can see on the 3rd line there was (or still is) some sort of checkvalve. What does each one connect to?

I assume you have deleted that.
It's a good place to connect your mechanical boost gauge.

The one on the right side of the UIM, just before the LIM, goes to a tee, to the waste gate, and to the pressure sensor (through an orifice pill).

OMG I am soo saving this thread!
I am getting my engine back from rebuilding and have to put the vac system togehter and I've never done this before!
Oh yeah the boost sensor line had that Restrictor pill note on it.
What is that? My S4 NA blocks line is too hardened to use. I'll be usuing some silicon vac hoses. Will there be any ill effects?

1) On the intake manifold (S5) there is a vacuum line that runs between the 2 secondary fuel injectors and then comes out the back side(engine back). What does this connect to because on mine it is already capped off?

6) On the back of the throttlebody there is another nipple that I don't know goes where.

Secondary injector air bleed. The angled one below it is for the FPR. I'm not sure what the other one is for.

So, in my case seeing this hose runs between the two injectors and then comes out the side (like I pointed out in the picture Motor2b) I connect that nipple to the top nipple on the Throttle body right?
I noticed maybe an error in your diagram, juts a labeling mistake perhaps. I think you mislabeled the oil injector air bleed and the thermovalve.
Just curious but speaking of the thermovalve (double throttle system), I did the TB mod, what do I connect this air bleed to now?

I'm putting my engine together tonight so just a recap.
My engine is a S5 block with S5 Manifolds and S4 TB with S4 front cover and Mech OMP.
I will not use my ACV and Airpump.
--Where does the FPR line from the Secondary rail go to? It's kind of hidden in that pic. Also the Secondary injector bleeds seem to go to the same spot.
--The front part of the UIM Vac hoses are plugged but one looks like it wasn't edited enough or it's supposed to go somewhere?
--Anything different for Vac between S4/S5 OMP's?
--The Oil injectors look a little different. Shoudl I use S4 or S5?
An answer was mentioned above but could you explain?
Also they said a Mech boost guage can be used through that one. The bottom one or one of the others?
Thx.

Purge valve help
I plan on keeping the charcoal canister after all. There are two hard lines that come off the purge valve that go who knows where. I am thinking to maybe on the left side of the throttle body. I circled in red where I think that they may go. Also, in that picture, are only the two bottom lines capped off? Where does the top one go to? Thank you in advance.
