O2 sensor wiring?

[jmarks99]

working on a 03 sport 4wd with 3.7 v6 and auto ******. Need to replace O2 sensor bank2 sensor2. However, the sensor is broke off and the O2 harness is nowhere in sight. How is this harness routed?

I had the same problem. The harness was unreachable so I had to cut the wires and splice on the new sensor. I'm going to re-do mine because I'm not happy with my splice job. Use a good connector, don't just twist the wires together and wrap them in electrical tape like I did

Even better if you could solder the wires together.

That's fine but how is it originally routed? Can't find the harness at all!

Can hardly believe no one here knows the answer to this question.

Harness routes from the engine compartment across the top of the transmission.
