Before getting my APR chip, I replaced the DV with the one from TT. After taking it out, I realized I didn't remember the exact orientation and did it this way:
1. Vacuum line - easy
2. Side line --> to the line going to the left (driver's side) hose, I guess to intercooler
3. Well, the remaining one (bottom) in the the line running somewhere toward the turbo area (I guess turbo discharge line).

Did I mess up? No strange sounds (chirping) when decelerating, but read somewhere that the side line is supposed to go to turbo.

According to this

I did it correctly based on this picture
