Thanks to all who replied to my call for help.  Last night replaced Digital
Idle Stabilizer and cleaned contacts.  In process found that connection on
Temp II was loose as locking snap on connector was broken.  Any ideas on
sourcing new connectors.  I have it temporarily glued in position.  Idle
more stable, but not perfect,

Also, when I went to replace aux.. air regulator, found that existing unit
was square and not round as replacements.  "Had "Made in Italy" stamped into
metal band around the unit.  Also, the two wires going in were Brown and Red
not Brown/Yellow and White per Bentley.  Can anyone help on this one.
