Working on my '84 K10 and trying to get the factory AC working. PO swapped the engine with a 400 sbc, so 90% of the factory vac lines have been completely gutted. I'm admittedly not very good at following these vac line diagrams but I think I finally understand it and basically just want to double check and make sure I'm correct on this. The hard plastic black line that comes from the firewall into the engine bay next to the airbox isn't connected to anything. I know this needs to run to vacuum for the vents to work. I also have factory cruise control and would like to get those lines hooked up as well. I drew up how I'm going to run the lines, just wanted to make sure this is correct.

Any help here would be greatly appreciated!

Did you figure it out? I’m in the same situation. Sweet drawing skills by the way!
