In the center, it's the climate control system.  Down by the pedals, it's the cruise
control.

If you have EATC, the vacuum soure for it goes through the very center of the top of
the firewall, from the engine side to the EATC side.  It is a small 1/8 inch black
line, that goes to the EATC.  There is a connector just before it goes into the
firewall.  From the EATC's rear side, a group of colored lines about the same size
branch out and go to the various vacuum loads.  Pull out the EATC head and check the
various lines in the back.  They all plug into it via a single plug that they all go
into the center of.

This would be a good place to start.  If you have the simple manual a/c controls,
they should be easy, too...but I have never been behind a dash that has that system.
