Default t3/t4 vacuum lines?

ok so i need some help with the vacuum lines. yes i searched but only came up with 1 thing usefull.
i know i can run the WG to the turbo. but my turbo doesnt have a socket/hole/input(what ever you may call it) and i found out i can run it to the intake vacuum line. (or cant i???)

now where can i run the rest of the lines too?

wastegate has 2 ports.. top and bottom. if your running a boost controller hook it up following instructions, if not bottom port to vac, best to get it from the compressor housing, or the charge pipe RIGHT off the compressor housing.. you *can* just run it to the manifold, but the best idea.

All other vac lines go to the manifold.

leave the top port open if you arent using a boost controller. vacuum lines are kinda self-explanatory. they go to a vacuum source, meaning the intake manifold.

i know the new search function sucks but there are a ton of FAQs covering this

The bottom port on Tial's dont like Vacumn, not sure what WG your using but generally a WG with a diaphram is only meant for boost, so hooking it up to a vacumn source is not favorable. If you cant drill and tap your compressor housing you want to source the line to the bottom of the WG to anywhere before your throttlebody, the Wastegate is looking for boost not vacumn.
