How do you connect O2 wires?

Important: The following is a text only archive!
For full features; Go to How do you connect O2 wires?

I purchased a generic 4 wire Oxygen sensor to replace my broken stock (94,000km Bank 1) O2 sensor on my P5. When the O2 sensor arrived I noticed the wire colours are different from my stock O2 sensor. The generic ones dont come with a harness so you need to connect it yourself. Can someone tell me which colour wires I supposed to match up.

IE: blue to grey

My stock O2 sensor = black, black, blue, white
Generic O2 sensor = white, white, black, grey

tough to help if we don't know make, model, model yr, engine, etc. posted by  tbaxleyjr

No idea, we don't even know what car you are working on or anything about it. Those of us that truely know what we are talking about are mechanical in nature. To fix a mechanical problem, most of the time it requires technical data to be available. The odds of you being able to get help with that are slim to none unless someone can jerk their crystal ball off and get an answer for you, I know I can't. We don't have any verification that you have even bought the correct aftermarket part for the car since we know nothing about it. Generic parts are exactly that....generic. Have fun! posted by  cmeseadoin

Hi Rhino1616, I have similar problem earlier connecting wires from an old o2 sensor plug with a newly purchased bosch. If you try to cut O2 sensor you are only welcoming more trouble. I just replaced it with an OEM designed sensor. It’s a bit expensive but serving me well still today. You may try likewise. posted by  cameliajuke1

I been there. When i got the new one it came with a color code book. The 2 black wires matched but there were a white and green on both and according to the book white went with green and green with white. posted by  DBain
