no one!? throwing code 2 cel (rear o2) since valve cover gasket replacement and have a track day on Thursday! my pins backed out of the connector and got out of order. All I need is a photo of your rear o2 harness connector to confirm the order. preferably a 91

currently I have the following
position harness - o2
1 green/white - white 2 red/blue - green
3 black/blue - black 4 black/yellow - black


I can even drop by your place if your between torrance and irvine.
 
Good luck amigo. How did your wires back out? If I can get to my car soon I can look, though I'm almost positive my 04 is different
 
thanks just figured it out seconds ago. turns out the upper two wires in the harness were flopped and not matching the service manual... so white from o2 goes to red with blue tracer and green goes to green regardless of position.

As for how it happened, it was whomever was in there last. I went to pull the connector and ended up with a handfull of wires.

It wasn't until i pulled the valve cover and found the connector pin retainer... which was dropped from someone flopping the pins on the engine bay harness for the new o2.

For anyone's future reference, 91' throwing codes 2 And 44

Good times had by all.
