3.4 swap o2 Sensors i need help /w wiring question

I have the o2 sensors and the wires off the harness EXCEPT

The wires are cut right at the motor and i need to resplice them into it i have a complete wiring diagram. Problem is.

The o2 sensors up stream n down stream both have a solid brown wire. And a white /w blue stripe. Which makes me confused on doing the wiring. except.

both brown wires meet up before they hit the ecu. Both white n blue meet up before the ecu. But do they send the same signals?

Whos got ideas for me or answers if im right that it shouldnt matter which matching wires i hook up?

Kind of confused b/c most I have seen are four wire O2 sensors. If just two then should not be a problem tying together same colors.
