The vacuum advance goes to and through the TVS to the "Ported Vacuum" port on the carb. If you eliminate the TVS then it goes direct to the "Ported vacuum" port on the carb. The ported vacuum port is the higher port on the driver's side front of the carb.

There is a picture of this hose connection in the GMC maintenance manual.
