Thanks for all of the help.  I got the schematic off of 311,org, fantastic,
found the one with the temp gauge on it, took it to Staples and for under
$20 I now have a foam backed laminated 18x24 colour wiring schematic.

With that in hand, I found the problem, a corroded connector on the voltage
regulator under the dash (thanks Pat for the location on that one).  After
cleaning, dielectric grease and a reconnection all of the gauges not work. 

I believe the AMP was already working but did not know it, I thought that it
should read in the positive while the car was running not neg and zero so I
believe that is now correct.

My next project is the high beams and low beams.  When selected to hi no
problem works fine, but in low they flicker between high and low, must be a
contact problem.  So I guess that I am going to disconnect and take it off
of the steering column and see if I can figure a solution.

Thanks again all, I greatly appreciated the help.  Final thought, where
should I post pictures of my car?

Chuck

Pat,  my copy has the temp send wire.  I have version 2 dated 12/10/04.  The
sender is labeled Thermal T/M and is right under the Voltage regulator.  A
yellow/white wire runs out of it.
