hvac vacuum harness

II recently replaced the heater core in my vehicle, during reinstallation one of the vacuum lines became disconnected from the hvac box (the black one). I do not remember exactly what actuator it went to and I would prefer not to have to completely remove the dashboard again. I am looking for a diagram or even better would be an illustration of the hvac vacuum system. Any advice would be appreciated, I will browse your YouTube videos, but I am afraid the information I am looking for will be to specific to be covered by a generic troubleshooting video.

Thanks,
