I need wiring diagrams for a Fairlady 280z

I have a 1979 Fairlady 280z 2+2 special edition and i need to find the wiring diagrams for that year and model. the existing harness is all but destroyed. I need to make sure that I have all the right sensors and enough wires.

The vaccum system in destroyed also. any help I can get for either of these problems would be much appriciated.

thanks
