Pull vacuum from the plenum attached to the throttle body. Grab boost from the plenum attached to the intake manifold.

The plenum on the throttle body should feed pcv valve a big line for all the vac powered stuff (cruise control, hvac controls) on the car, and the bypass valve. Fuel pressure regulator and boost gauge should get fed off the plenum attached to the intake manifold.
