I had to replace the plastic connector on the harness side of my O2 sensor. I think I may of F-ed up the wire order. Can someone let me know which wires on the harness correspond to which wires on the O2 snesor? Any help would be much appreciated!!!

If your harness colors don't match that schematic separate them and turn the key on. Find the two that have 12 volts and connect them to the two same color (usually black) wires on the sensor. Doesn't matter where each one goes. Connect the remaining harness wire to the remaining wire (usually blue) on the sensor...

I did see the manual and my wire colors were different.... (the owner before me hacked the harness) but I will be able to fix the problem now, THANKS!jetjock;1321712 said:
