Does anyone have a vacuum diagram for the HVAC system? (1983 K5)

I’ve looked high and low and can’t one anywhere. I found what I think I need on google but the image is to blurry to make it out. It’s winter and I took the truck out today and about froze my ass off! I’m getting some heat but I’m missing vacuum lines to the diaphragms for the doors in the box. I have about 30’ of vacuum hose that I got last summer but never got around to doing this project and now the below freezing temps have motivated me. It’s a factory AC truck, not sure if that makes a difference.

It’s not In the service manual?
You can download them for free from the other site.

Not sure? I would think they would be somewhere but my search left me with nothing.

If it's not online, i have an 83 service manual. But it will take me a few hours or more to scan it in.
