I have two questions. Our three sensors were powered with the black and white wires tied together. Can this destroy them? One does not seem to work properly.

After this error was found we bench tested two of them. We hooked one lead of a digital multimeter and the sensor's brown wire to +12 from the PDB. The sensor's blue wire was connected to the - of the PDB. The other lead of the meter was connected to the sensor's black wire. One showed +12 when the sensor saw or did not see the target although the indicator lights reacted, apparently bad. The second sensor we tested went from +12 to a reading of about 3 volts that drifted up to about 8 volts. Could the second one's strange reading be a result of using the meter as a load? We will test it on the sidecar tomorrow but I am curious about the reading.
