ok homie only 2 lines. This is an easy one.

The line in which will be coming from the top intake mainfold plenum will supply you with your vaccum. That one will go directly to the boost controller. Place on the one with the arrow.

The 2nd line will go to the wastegate.

TA DA YOUR DONE! the "T" is probably for a secondary vaccum device such as a bov but i wouldn't suggest it due to comressor surge. But it make one hell of a fluttering sound. Scares the crap out of people when my hks ssqv flutters. Especially when i'm on the highway.
