Vac Lines - HELP!
 

I have a vac inlet on my turbo, 2 on my wastegate (side and top), and 3 on my boost controller (one in, one out, and a smaller vac source by the knob)...

What do I hose up, and what do I leave open?

I have a Tial wastegate, a garret t3/t4 turbo, and a non-labeled manual boost controller.

is it a mechanical boost controller? leave the top of the wastegate alone (vent it to the atmosphere) the side one will run to a source of vaccum, in this case it will be going to your boost controller but since you have 3 vaccum source on your boost controller i am unsure since im only used to ones with 2 vaccum sources

on the ones ive used, the side of the wastegate goes to the vaccum source on the boostcontroller that has the bleeder valve (sometimes a tiny pin hole in the side of the controller or hose barb), the other one you will run to a source of vaccum (you can put it on your turbo inlet or on the intake manifold, or fpr line)
