Rooster2 Posted May 17, 2013 Share Posted May 17, 2013 Is this from the front or rear O2 sensor? I just replaced my rear sensor that is a three wire unit. The sensor wiring and connector wiring are color coded the same. So, the colored wires matched up the same upon pushing the connector together from the sensor pig tail to the car wire harness (receiving) connector.

O.you it looks correct, the part numbers for the upstream o2 sensor are the same on both years Thank Quote Link to comment Share on other sites More sharing options...
mightGETaSUBARU Posted May 21, 2013 Author Share Posted May 21, 2013 weird mine are White, White and black Quote Link to comment Share on other sites More sharing options...
ocei77 Posted May 21, 2013 Share Posted May 21, 2013 Not a big deal. Sometimes they change wire colors between years. As long as the left wire on top is the white one, all else follows in sequence. O. Quote Link to comment Share on other sites More sharing options...

ocei77 Posted May 22, 2013 Share Posted May 22, 2013 I "assumed" the harness side pulled out. I will have to pull it in the morning and see what goes to where on the sensor side. O. Quote Link to comment Share on other sites More sharing options...
ocei77 Posted May 22, 2013 Share Posted May 22, 2013 (edited) if the plug side pulled, the white wires go to the top two pins. Black to bottom. They should still be in the correct orientation. O. Edited May 22, 2013 by ocei77 Quote Link to comment Share on other sites More sharing options...
mightGETaSUBARU Posted May 22, 2013 Author Share Posted May 22, 2013 So it does not matter what order the whites go in, so long as the black is in position 3? Ok thank you Quote Link to comment Share on other sites More sharing options...
ocei77 Posted May 22, 2013 Share Posted May 22, 2013 (edited) One white goes to ground and the other goes to pin 38 on ecu., when mated. I can't say it's gospel, but I don't think it will matter which goes where, since there are no other circuits in between or connecting, except ground.
