I am currently trying to find a vacuum leak in the system. Does anyone have a vacuum diagram for an 84 300TDT. I have a solid black vacuum hose going thru the fire wall together with the A/C, door locks, ignition vacuum hoses. The diagram on the cowl doesnt show where the black hose leads to inside under the dash. When I looked under the dash, cant seem to find where it is attached. Can anyone help me with this.

It's a vent. Not attached.

Try this for a diagram:
