I have an 86 Bronco 2 that I would like to change the O2 sensor on but... the previous owner cut the stock wiring harness for the sensor and spliced in a something else, maybe a universal type. I don't know which wire corresponds to which. I talked to someone at NTK and they told me which wires are what on the new sensor but I don't know about the wiring on the Bronco 2. I have what appears to be (as best as I can tell) a Black, Yellow and Green wire to the O2 sensor. Any info on this would be great.
