Chuck,
Yes, you want the upstream sensor. I believe you want the grey wire.
(the white ones are for the heating element, I definitely know you don't
want either of those) the black would be the ground. (I think... I
don't recall if the black was ground or if the grey was ground.) If
your FSM says its a dark green wire with a pink stripe, pull some of the
protective covering back at the O2 sensor plug, find that wire, then see
wether it corresponds to the black or the grey wire. An alternative is
to tie into the signal wire in the engine bay. Just find the proper wire
(would seem to be the dark green/pink one) going into the PCM and use a
crimp tap or something right there. No need to go all the way back to
the sensor. (That's how I did it.)
