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.

Yo,

Ok, I added info that to your profile.

Also, as built transfer case is Borg Warner (BW) 1350 manual or electronic (shift-on-the-fly, aka ESOF) unless you have them 2wd model.

Front 4WD axle is Dana 28 TTB; rear axle is Ford 7.5"; firing order is 1-4-2-5-3-6;

distributor rotation is clockwise;
