Vaccuum lines 86 Monte Carlo SS

[dand]

I am almost done with my ground up restoration 4 years! I am at a loss for some of my vacuum line routing. There is a bal on the drivers side with one fitting, I know it is a reservoir but I don't know how it connects. Also the purple line from the heater control, where does it connect?
The schematics I found don't show the ball and heater controls. I think the white plastic line from the heater control goes to the water valve. I think I got the rest of the lines figured out, just lost at this point. Any help would be appreciated, even if some on could take pics of their engine compartment.
Thanks
Dan
