What's the vacum hose diagram look like for the greddy turbo upgrade or any upgrade? Need to hook up boost controller, external wastegate, and pressure sensor as well as the intake manifold. Which goes to which? Any help would be greatly appreciated!!!!

 

External gate goes to the 'out' on the boost controller.
The 'in' on the boost controller goes to a vacume source, IE intake manifold.
Pressure sensor, senses pressure, so hooks to vacume source on the intake manifold again.

BOV's goto the vacume boost source like the intake mani-
