Does anyone have a vacuum schematic for the 85-86 model years?
Also; for the same model years, there is a vacuum hose connecting to the intake manifold that is visible in between/underneath the front manifold tubes. It looks like it may be removable via a long spark plug cable remover type device. Is attempting to remove it risking an unplanned intake manifold removal job?

Be careful when working with the vacuum line to the transmission. Mine had a rubber connector at the front of the torque tube joining the hose from the 7-way connector to the longer hose from the transmission. It's in a difficult spot to access, so when I accidently pulled the engine bay hose out of that connector, I was spewing profanity for about an hour to get it back together.
