motor bareblocked...so where are the vacuum lines?

building my car and motor from scratch, i decided to do off with emissions and the oil metering pump.
i believe there are supposed to be three vacuum lines? i just dont know where exactly they are and how they're routed.
i've gone over the rotary resurrection writeup numerous times...it'd be no problem and make sense if i had all the emisisons **** on my motor to begin with, but i havent.
any pictures/help/links/other useful threads i may have missed would be greatly appreciated!
i'm ready to fire this bitch up tomorrow.
thanks guys

I know you need the MAP line from the passanger strut-tower; and the FPR from the secondairy fuel rail...

...I think that's all I ran on mine, but mine has no snail.

Scroll down and look for my post. I think I've described every vac/pressure source available after deleting the rats nest

You missed the fuel injector air bleed line(s). The S4 has one for the primary injectors and the S5 has them for both primaries and secondaries. They're there to improve fuel atomisation, which improve engine efficiency. There's no advantage to not running them.
