ok, i had a post earlier about my 4 wire 02 sensor, then it got off topic about a different code i was throwing, so here goes

the conversion harness wires that go to the 02 sensor are: black,red,blue,white
and the 02 sensor colors are white(2), black, gray

the instructions for the obd1 conversion state that the blue=02 heater, red=02 power,black=ground, white=02 signal

The bosch sensor states that the black=ground,gray=signal,white(2)=+/- for heater element

Now, would it matter if the +/- wires for the heater element are mixed up? say the blue was hooked up where the red was?
