Bought a 2000 Trans Am smashed about 2 and a half years ago just slowly picking at it, the vaccum pot for the hvac is gone completely and the lines aren't close by either, I can see the line coming from the firewall that is supposed to go to the vaccum pot, but I have no idea where the other line is supposed to go to(vacuum pot to vaccum source), I'm assuming somewhere near the intake manifold or brake booster?
