Don't you remember those two groups we put everybody into, and that I was in
the one that didn't have a manual and used the list as a surrogate for
thought...ie a second brain if you will...

As it where, I did check the copy of the appropo Bentley page I have (sorry
Chris), and it does have the terminal #'s I was looking for, but not the
voltages.  Also, from Matt's reply, I also found out that since I'd last
printed out the page on the topic from Scott M's site, he had updated it
with these termianl #'s.  I was just going in swinging and using the ECU
connector page I'd printed from Scott's site...and that's where only one
connection is listed for the temp sensor.

...long and short...I just didn't remember using info from the bentley last
time I went down this troubleshooting path, and as such didn't check the
