Hello to everyone I have 1992 Pontiac firebird v6 3.lt can anyone tell me where o2 sensor connector connect because my car gave code for o2 sensor I went down to the car and connector is just hanging in a air and there is no connector where I can connect my o2 connector.
Or is there any wire come from other sensor which can lead me to o2 sensor wire

 

If my memory serves me correctly, it should be hanging somewhere along the transmission. It's a single wire that splits off from the main harness and runs down along by the transmission on the right (passenger) side of the car.
