SR20DET vacuum lines question?

[240sx240sx]

Ok on the SR20DET into a s13 chassis;I know the bottom nipple on the T.B. gets plugged.

The small nipple on top tees to the FPR - then to the boost gauge ///then tees to the press. port on my boost controller?/// Is this ok to have 3 tees on 1 line?

The big nipple goes straight to the BOV no tees inline here

Ok then the wastegate gets its vacuum from the I/C piping - only thing is my I/C piping does not have a nipple for this - so where can I get my vacuum for it?

Does it need to be before the T.B. or after the T.B.

Any help would be great - I did search and could not find anythig with my setup?
