Purple wire. Look under hood and find the wiring harness that goes to the O2 sensor(easiest is on pasenger side) Its purple. Follow it back to the midway point . I tapped into it . Very easy.
Driver side is purple and white .
Driver side is purple and white .

Both O2 sensor signal wires go to Connector "C" (grey) on the PCM. Drivers side is purple/white wire to pin C20. Passenger side is purple wire to pin C8. Splice into both of them, run them to a single-pole/double-throw switch, and you will be able to select either sensor for the meter.
