Setting rear O2 sensors to act as bank 1 (primary) O2 sensors

[T34418L31]

Hello all,

I am building an LS1-powered car, and the longtubes on the car have the O2 bungs in the collectors. As such, I will either need to extend the primary O2 wiring harnesses, or (hopefully) use the rear O2 sensor wires as the primaries.

Can this be done? I searched a bit and found a thread suggesting to simply turn off the MIL for the rear O2's, but this doesn't seem like a complete fix. Is this the popular way of having the rear O2 sensor wiring acting as the front O2 sensor wiring?

Thanks, and sorry if this has been covered. I did search, but found a lot of "how to turn off rear O2" threads, not much pertaining to my question.

Swap the front O2 wires with the rear ones at the PCM connector.
