vacuum lines at air box and radiator / alternator wiring 700 1989

hello all-
almost done replacing the engine.
there are three vacuum lines at the air box whose final orientation i am unsure of.
there are two coming out of a circular white unit with an electrical connector. my guess is that one of them connects to the turbo waste gate vacuum t-fitting. there is a little hole on the bottom of the air box. does the other vacuum line from this unit go there? also, there is a third that comes from behind the headlight. does this go to the radiator?

does anyone have a good diagram for the wiring of the alternator and A/C compressor? or tips? i am unsure of what goes where.
