Re: Secondary O2 sensor?
What exactly are you asking, rereading through your first post confuses me terribly.

Whoops sorry jbpnoman, I guess I missed the fact that he already has the cabin harness.
t-del28, the plug for the secondary o2 sensor should run through the chassis where the shifter is

Re: Secondary O2 sensor?
Also, i was looking everywhere even by fuel pump area? I had this reason for power window.
...so its wires harness connect with obd2a P72 Ecu.
FYI OBD2a require primary o2 sensor AND secondary o2 sensor.
Like i said right now my secondary o2 sensor is on catalyic converter. The
4 wires is now through a hole between by shift linkage/airbag brain module.

Re: Secondary O2 sensor?
it's part of the dash harness not the floor harness maybe if you gave us some more info like what year,body style and trim level your car started off as ? . the plug on a stock harness is located on the left of the lower center panel behind cup holders beside the srs module and there is a small jumper harness (flat 4 plug to square 4 plug) that goes between the 02 and the dash harness.

Re: Secondary O2 sensor?
I still have no clue what you are asking? Is English your first language?

Re: Secondary O2 sensor?
Check on the chassis over the cat. There should be a hole around the area where the shifter is. Based on what I've read, that's where the hole for the 2nd o2 sensor should be. The wire clip shouldn't be far from there. Hope that helps

Re: Secondary O2 sensor?
yeah if it IS an ex dash harness then the plug should be hanging by the cat/shifter. just plug it in no wiring. im not sure why your even looking behind the cig lighter. under the car by the cat look around if you dont see it its either a different harness or the harness has been cut (not sure why someone would cut the secondary o2 sensor connector off though)
