which is which lol white=signal, blue=ground black=positive and neg for ground? i read on a troubleshooting site for p0125 that a faulty heated o2 sensor can cause it.? maybe the retart mixed up with the two black wires when extending my o2's?

when you buy a sensor there is a chart on the directions.

well if anyone needs help with this code like i did i found out it was a bad a/f code from a bad o2 sensor so watch out.
