I am needing to replace my rear OS2/Lambda Sond sensor. Going OEM is really costly. So I have being looking at Bosch/NGK After market ones. Downside is that they need to be wired into existing harness. Which is no hassle to do.

I would like know, if anyone knows which wires are which. 4 wire, 2 black, 1 white, 1 blue. Is the original one I am taking off (15yrs old, not bad run).

Any help would be great!

Cheers
