Vacuum diagrams for A/C control to plenum door actuators --73 Century

Can anyone enlighten me on just where all of those nice little color coded vacuum lines go? I imagine they'd be shown in a chassis manual, if I had such an item. I'm retrofitting a non-A/C car to factory A/C, and have the control head swapped, but need to hook up all of the vacuum lines.

I also need some ducts and associated widgets, and I've put a post in parts wanted, in case anybody reading this has any parts..

Thanks!

I found the vacuum diagram in there, along with a bunch of other helpful diagrams and views. Tomorrow I'm headed to look at some mid 70s Pontiacs in the local junkyard in hopes that I can find some of those ducts.
