Just bought an O2 sensor for my motor and have no idea which wires are which. It didnt come with a plug so I have to pin it myself. As shown there is a Blue, Back, Black, White. The stock Civic harness socket has Green, Orange, Yellow, White. (Dont mind the wire that the O2 sensor is connected to in the pic, I just had some old wire I used.) Anyone know what wire goes where?

 

What brand sensor? Any serial numbers? This information might lead to the answer.

 

Yes, Ill try to look this up too...

I think this site shows you how to wire your type B sensor to a Honda.

 

Thanks for you help sir, I should be able to sort it now.
