O2 sensor wiring question....

[CudaJimmy]

Well, someone clipped off the pigtail that connects to the back O2 sensor on my 02 TJ. I think it happened at my wifes work (police department). Comforting, huh?

ANYWAY...

I bought a new pigtail at the dealership, but all the wires are the same color. Can someone post up a picture of the pigtail so I can get the wiring correct? This is the pigtail that plugs into the BACK O2 sensor. The pigtail that's actually on the sensor, is still there.

Thanks!

These are both downstream O2 sensors since you said it's the one on the back..
