Unfortunately there aren't any diagrams for your vehicle that show specifically where the brake boost vacuum hose attaches. In most cases though, that particular hose should connect directly to the intake manifold somewhere on the engine side of the throttle body. If you start the engine with that hose disconnected, you should be able to hear and locate a fairly significant vacuum leak.
