I'm going to install a new 02 sensor today, but it
struck me. There are
=
2 white wires and 1 black. Does it matter how I splice
up the white =
wires?

TIA,

Don,
    To do a job like this, it is a good idea to have a
meter to measure and confirm the wiring.   The two
white wires should go to the heater on the sensor
which is 12 volts and NOT FUSED.  The heater warms the
sensor to make it work sooner.   The black wire should
have about 0.5 volt coming from the sensor when the
engine is running and warmed up.  Like any heater
there is no polarity but if you short the wire against
the frame or worse yet across the senor wire you can
have problems.
I confirmed the voltages before taking the old sensor
off, just to be safe.   I also offset the black wire
splice away from the two white wire splice.
         good luck gary
