The O2 sensor connector/plug on my '96 Mystique V6 has lost the insulation on some of the wires and they're fraying. Unfortunately this is happening on the side of the connector that is part of the vehicle wiring harness. If it were the other side, I'd simply replace the sensor and the problem would be gone. It's the upstream sensor, I'm not sure if it's bank 1 or 2. It's the one on the firewall side of the engine.

Making repairs can be tricky due to the fairly delicate nature of the sensor and it's sensitivity to voltage changes which can be affected by resistance in the wires. Anyone know of a repair for this? Where I can get a new connector?
 
I'm having the same problem. Here in AZ, rabbits have chewed the wires on the engine side of my 02 sensor. I foolishly failed to take a picture of the initial situation because now I have no idea where the 4 wires connect. To no avail I have been searching for a month now for someone who sells the engine-side pigtail. I'm attaching pics of both.

Need any suggestions from you CSVT gurus.

O2 Wiring harness connection

Background:

Rabbits chewed through the wiring harness wires that connect to the upstream O2 sensor. I had replaced this pigtail connector before, but forgotten to record the original wiring diagram to know which wires attach correctly to the pigtail connector.

Here is a photo description of the problem: http://bit.ly/bRM5nq

Does anyone have a photo of an OEM connector?

Thanks to @Beans @JHowell & @tvissoc
