Okay so my drivers side rear O2 sensor is going bad because the wires are frayed.

My question is whether the drivers side rear sensor is for cylinders 1,2,3 or cylinders 4,5,6?

One of them costs like $60 and the other is like $160.

The DP closer to the engine is cyl 1-3, and the pipe farther from the engine is cyl 4-6. Bosch 16795 for cyl 1-3 and Bosch 16796 for cyl 4-6. Bank 1 has the LONGER wire of the two.

This is a little confusing because there pretty much parallel, one on driver side, one of passenger side. If by closest to the motor you mean closest to the front of the car then I can understand that.

Perhaps I will just go under and see which has the longer wire.

I mean when you're under the car, the one closer to the center of the car (medial) is bank 1 and the one closer to the frame rail (lateral) is bank 2.
