Default Cruise Control Hoses 1986

Sorry second time around on this on my 86. The cruise control module has two vacuum connections on it. I am trying to figure out which port goes where. Right now there is a line that runs from the canister in front to the check valve near the dist cap. In the middle of that line there is a tee fitting which I assume a line from there comes up to the CC module if this line is even correct. So my questions are:
Is the line as described above plumbed correctly?
If so, which port of the two on the CC module would the "teed" line go into?
Is the other port on the CC mod left blank or open?
If not, where does the other end of a hose connect to this port connect to?
Is there a rule of thumb on the adjustment of the cable on the CC?

As always my membership to this forum is greatly appreciated as is your help. Thank you very much.

Is an 84 the same system?
If so I will take pics later in the week for you or PM me and we can talk on the phone. But only if the 84 is the same.

Thank you. I see now the end I am trying to figure out goes to the brake pedal.
