Modified Vacuum Diagram Question

[Exoboy]

Hello everyone! I plan on running the vacuum setup shown here http://z32.wikispaces.com/file/view/TT_ ... roller.png

I have followed all the necessary steps and deleted the AIV, PRVR, EVAP, and EGR. I am also running an EBC. My question is that in the diagram where it says 'to throttle body,' which pipe is that? I thought the hoses going to the throttle body were just boost hoses and have no vacuum nipples. I have the accordion pipes and there are three nipples title, as shown in the diagram, but I cannot find the two 'to throttle body,' nipples. Is that off of the intercooler piping? If so, which pipe? Thank you!
