air pumps

ref: Carl Summers   7730 Air Pump
Last material I had was that during warm up the air pumps
"air" was injected at the exhaust manifolds to help with
"afterburning" the rich cold start mixture, this was to quicken
the heating of the O2 sensor.  Once "warm" (coolant temp)
the ecm would switch the air valve so that the air pump 
discharge was diverted to the center section of a monolithic
converter, or upstream on a pellet type converter.
  With the O2 cold there would be no "readable difference"
in O2v..  When warm it would be downstream, again no
O2 difference.
  The only connection my diagram shows is F2 for grounding the
air select solenoid, so I'd venture a quess of 200 ohm resistor to
12v would solve that.   Might double check the OEM solenoid's
tend to be 90 ohm.   Generally doubling the resistance has worked
for me, on other items, to turn off diagnostics when code not 
available.
  Any one else's input?.
