1995 Eclipse RS automatic with 2.0L engine.

Purchased as a project and trying to figure out multiple things at once. It has an aftermarket header and the downstream O2 sensor was deleted, but I cannot locate the connector/pigtail for it anywhere under the vehicle. I have the carpet removed in the car, which makes it a bit easier to look at things. Where should I be looking for this connector? Where does it originate from? Do you have the wiring diagram that includes it?

Thanks.
 
I believe the downstream o2 was only present on the manual 420a’s. The wiring runs down the left side of the center console and goes through the floor pan beneath the driver’s seat. C-15 is the connector in the pic.

Thank you. Makes sense why I can't locate a connector anywhere, but will look closer at the center console now to ensure there isn't one there.
