Default 1.8T vacuum tubing diagram despirately needed!

Hello. Can somebody please e-mail me with the vacuum tubing diagram for a '97 A4 1.8T. I'm removing my boost controller and trying to hook the vacuum tubing up to the stock configuration so I can run with a chip. I need a diagram for the turbo and blow off valve hook up to the engine and car. Thanks a lot!

Default BTW 23,25,26 and 27 are the areas most likely to have been tampered with just FYI

Default James - Do you have the ECU maps for the 97 A4 1.8?

James-
Where do you get this great stuff from? This is awesome. By chance, do you have the ECU maps for the 1.8t? I need the maps eventually to hook up my A'PEXi Super AVC-R boost controller. Mostly need the maps to hook up the RPM monitor (I think). Thanks again!
