Wiring going into exhaust?

[Chris Pettyjohn]

my son has a 2002 ram 1500 with the 5.9 gas engine. We had to replace the front seal on the transmission and while pulling the transmission we ripped out the wires of a wiring harness that has wires going into the exhaust pipe. I can splice the wires back in, but i have zero clue what wires go to what. The wires on each side of the harness are different colors which makes it next to impossible without a wiring diagram which i can not find. Any info would be greatly appreciated.

The whole assembly is just draped over the tranny. The side coming from the engine area is Green with a white stripe, gray with a white stripe, white and black. The other side that goes into the exhaust pipe is gray, white, white and black

Exhaust Temp Sensor?

O2 sensor wires

Secondary/Post Catalytic converter Oxygen sensors are there to verify the cats are functioning. Will immediately throw a light for no feedback without causing drive-ability issues, but I'd personally just order a whole new secondary O2 sensor with plug so it's a direct swap instead of dealing with picky resistances in the circuit.

Thanks everyone, i was able to find the part online and look at a photo of the harness to rewire it as needed. Thanks again for the help.
