Default Front and Rear oxygen sensors the same?

I am building a harness right now and I would like to use the rear O2 sensor wiring for the front O2 sensors because I am running long tubes. My reasoning for this is so that I can avoid lengthening the front O2 wires.

My question is, Can I run "rear" O2 sensors as "front" O2 sensors? I know they serve different purposes, but, do they read differently?

I knew I would have to switch the pins, much easier than cutting/splicing.
My question was more towards the functionality of the oxygen sensors. I read the thread about switching the pins on a F-Body, but they use the same connector between front/rear. My harness is a truck harness and the connectors are different.
