Exclamation new car doesn't have vacuum line on BPV! help!

i just purchased the car last week and i just finished replacing the PNP switch on it, when i finished i took it for a test drive but then i heard the turbo surging so i took it back home and took a look at the turbo and i saw the BPV with no vacuum line going to it, where does the vacuum line go i cant find a empty slot on the vacuum tree on the throttle body... where is it? thanks!

Hopefully these will help.

The blue hose goes to the air filter housing or a nipple on the intake tube. Can't remember off hand. It's just a source of clean air.

I think the line your concerned with is the red line and that should go to a nipple on the throttle body. It's at the bottom buried under all charge air hoses.
