Heater control vacuum line on 1995 Tahoe 5.7

[Cu42]

:help:Hi guys, I need your help to find how the vacuum line that connect the heater control valve runs. I just found this line is missing and do not see any open port where this could connect to. The diagram on top of my radiator doesn't show this area. Thank you guys, I wish a very happy New Year for all members of forum.

Not sure if the TBI is set up the same way, but on my 98 the vacuum line connects at the PCV valve fitting and runs over to the solenoid on the firewall. There's a second line (I think it is 1/8") that connects from the solenoid to the valve.
