Default vacuum line

the vacuum line that runs off the back of the intake t's over by the pcm. the one line runs back to the firewall and the other runs with the wiring harness. where does the one that runs thru the harness go to?

on my car from the T there is also a line that runs in the harness along the fender of the car. it ends up somewhere either in the front of the car or over on the drivers side.

That line going into the harness is for the A/C. After it goes into the harness, there's yet another T. One side goes to the vacuum canister, which should be behind/below the passenger side headlight, other side should go inside the HVAC equipment to operate the a/c flapper.
