So I am trying to figure out where my brake booster vacuum tie in will be for my S5 Turbo UIM. My UIM has pretty much everything deleted on it. I know the brake booster connects to the metal pipe that runs along the firewall, but I can't find anything that I feel that it should connect to on the UIM. I have searched through here and the fsm's for vacuum routing, but nothing references the brake booster. Am I missing something that's been deleted?

Thanks.

 

it is on the Upper intake manifold , and not the throttle body.
