Default Vacuum help

I have been looking and can' seem to find it. I need to know where the hard line (metal tube at the back of the motor) for the transmission gets it' vacuum feed. Mine got melted and the hose is a awol. Can someone help. Oh this is a 90 model with a 92 engine.

also anyone have a decent vacuum diagram so I can fix some of the other issues when I get home

On my '00 model there are two metal lines, but those are vent lines for the EVAP system that runs back to the charcoal canister.

I can't remember why there are two. I think one's for vacuum and the other is check valved for an air inlet to disperse the vapors with.
