O2 sensor connector wiring diagram
So I ordered an ac delco connector for my upstream o2s and it came it and it’s all grey so I’m playing the guessing game atp got my car running fine for 4 days then it started throwing bank 2 lean codes. Found a burnt wire on passenger side o2 harness did the same thing I did to drivers side orderered a connector sautered if on started the car and it’s pissing black smoke idling at 300rpms as soon as I press the gas stalls and won’t start up again. Need the wiring diagram for the connector idk what pin goes to what from o2 side to o2 sensor connector since it’s all grey any help would be appreciated.
