4ks OXS-system connector problem?

[roger@mostro.sps.mot.com (Roger Albert)]

Hi all,

So, I'm just starting to get a chance to poke around the motor of last month's
'86 4ks acquisition to cure my horrible part-throttle stumble.  Also, now that
its cool (50-60F) I have to wait at least a full minute before I can drive off.
If I feed it _any_ throttle, it will stumble and/or die.  Just won't rev above
idle at all.  It does however start and idle perfectly.  Seems to be going very
lean, I'd guess.  

Anyway, my initial poking around revealed a connecter near the intake boot 
that wasn't connected to anything, but was broken and corroded.  At first I 
was sure I'd found the problem, but I then realized I could find absolutely 
nothing to plug it into.  I pulled out my newly acquired, but as yet unread
Bentley and believe I have identified the connector as T2A.  Its a two pin
white plastic sort of Molex looking afair.  That, its location near the intake
boot, and the wires coming out of it (G/R & B/R, with one of them actually
being a pair, can't recall which) is how I identified it.  If I'm right, both
go back to the main ECU, but the dual-wired terminal pigtails back to something
called an idle stabilizer valve.  

I'm not familiar yet with the wiring diagaram conventions in the manual
(like, of what use are track numbers and what about those numbers that go
across the bottom of the pages, sequentially?) but it appears that maybe
this connector is supposed to be unattached.  Might also be that it goes to 
a connector on another page I haven't found yet and I'm just not interpreting
the diagrams right yet.

I'd be mucho appreciative of any help specific to this connector, its relevance
to my problem, or on Bentley wiring diagram interpretation in general.

Thanks bunches.
regards
roger
