First, thanks to all who helped me with my
exhaust system.

I bought a good looking o2 sensor from fcpgroton.
It is made by walker. On their site they said
this for the part info:

Universal 3 Wire Oxygen Sensor will fit all 85-92 models.

When they said all I thought they meant ALL. and maybe they
do, but I found and old post on the bboard about titania
and zirconia cores and something about regina being different,
which I have. I still could not determine if I bought
the correct one from that post.

Well anyways, my old o2 sensor has a black, white and red
wire. The new sensor has a white and two black wires.
If it is correct, would anyone know what wires to match up?

I have a electrical engineer in the family, and it might
be possible to convert the electrical signal if I bought the
wrong sensor, but Im not sure on what kind of output im looking
for and what the signal range is. If someone good shed some
light on the subject, that would be great.

Thanks,
Jon
