wiring help

I have a 1980 Firebird 3.8L and I am putting a 383 stoker in to it. I stumbled across an instrument cluster for 1979 Trans Am. I know the printed circuitry is different so I am going to wire everything separate, but I need a wiring diagram for both cars so I know what is what. I have looked at many different restoration catalog and I have talked to all of them and I can’t get anywhere with it. I am hoping you all can point me in the right direction for some info on my issue.
Thanks,
Ron

If you want your own, my best suggestion is taking a stroll around your next local swap meet.

Other than that, sometimes you could get lucky at the library.
