technical questions to steering gearbox and vacuum gauge on a 1965 grand prix


lets try a second time.
My name is Stefan, I am from austria and I am owning a 1965 Pontiac Grand Prix.
I am restoring oldtimer for around 12 years now, but the pontiac is my first US-Car.

Because it isnīt that easy to get spare parts here in europe, especialy in austria, I have to ask first instead of just try and destroy something

So here are may questions:

I have a vacuum gauge in my car, but it is not working.
I think I know why its not working, but I am not sure. How are the vacuum hoses routed in the engine department, and which parts have to be connected with which ones? Perhaps somebody could send me some detail pictures ore a drawing of a workshop manual which shows the complete installation of the vacuum hoses.

Is there any posibility to adjust the stearing gearbox?
There is a screw on top of it, on the outside there is a nut, and inside the nut there is a kind of Torx-screw. I am not sure if i can adjust the steering with that screw (maybe I should post a picture of the screw I am meening?)

And the third qestion I have, does anybody have an electric wiring diagram of the car, that would help me a lot.

Thanks for your help,
with best regards
