Which O2 sensor?

[sbsrlewis]

I have a 92 Explorer 4.0 in a 89 BII. Still has the BII exhaust. Should I be using the O2 sensors for the Ex or the BII?

Thanks
Steve

They are probably the same, but I'd say which ever vehicle the computer is from.

Simply put...it really doesn't matter, they all do the same thing. Use which ever one plugs in.
