I suck, need some help with vacuum lines

I have searched a bit through dsm.org and vfaq but havn't found an actual diagram or any literature on how the vacuum lines for boost control solenoid, wastegate actuator, IC pipe nipple, etc are routed. My car is completely stock, I took the air can out to get to the 4ws lines to remove them and I can't remember how the vacuum lines go back on /ubbthreads/images/graemlins/banghead.gif . Any help would be greatly appreciated.

I know, I'm the sh*t.

edit: btw, there is a diagram under your cars hood, although that does not show the IC nipple vacuum line.

The diagram is slightly off. On a GVR4 there's an extra "T" between the turbo and wastegate with another vacuum line that connects to the intake near the BOV. Simple trick on a stock car is to cap the pressure source on the turbo, remove one "T" and only use the post intercooler source to gain ~1psi of boost.

Here's the one from my manual showing the extra "T" and post-intercooler pressure source:
