those with 99-00 Si's...
what harness does you secondary o2 tie into? is it the main engine harness or is it something in the cabin? pics would be HUGE if you have some. thanks a lot for anyone who can help me out.

it ties into another harness. The engine harness only goes into the engine bay from the ECU. I think the 2ndary O2 sensor harness goes into the green plug harness at the ECU.

doin a jdm or usdm based engine, i am in the midst of a 99 swap and only one o2 is needed, but if you are doin a usdm engine you will need that.

yes...i am staying obdII...and i would love to know where the harness ties into. anyone comment on the 'green plug' theory? from seeing how long the harness on the stock o2 was i assume it has to run up into the cabin right around the driver side floor...but then where is beyond me right now?!?!?!

Actually, I think I'm wrong. I forgot that there is a harness that goes into the car on the driver side. I think that is where the 2ndary O2 wires feed through. But I think they go from under the center console to the driver side to the engine bay to the ecu.

can anyone actually see what harness it ties into and where? i am trying to get an idea so i can make it truly plug and play...hard wiring is not working for me. this is the secondary i am talking about...keep that in mind.

I'm not sure where it comes from, but I know for a fact that it doesn't come of the engine harness. It goes straight into the floorpan for the o2 sensor.

ok...i got the through the floorboard part. how exactly does it get to the ecu? the o2 itself has a very short harness...so is this something that only comes on the Si? i ripped my whole entire interior out tonight on found nothing that even resembled the plug on the o2.
