1991 Olds Cutlass Supreme - Where is the vacuum line that goes from the engine compartment to the solenoid block under the dash? Where does it go through the firewall?

Our database does not show the exact location but it should be somewhere near the center of engine compartment on firewall. If you look closely, you should be able to see a rubber grommet throuth which the vacuum line goes through.
