Looking for some diagrams?

I'm looking for the layout or diagram for the Emission and vacuum systems on an 84 Canadian GMC. I'm also looking for the diagrams for the wiring running down the passenger side cylinder head, the wires that go to the alt and starter and everything else in that wire loom. I'm looking to clean up my engine bay and reroute some of the vacuum lines and wiring.

Thanks again John. Do you know where I can find diagrams on the vacuum and emission lines?

Mine is still on the core support, but very mangled and hard to read.
