I was wondering if anyone knows what wires are what on the O2 Sensors?

I'm having to replace my rear sensor, and $250 is a bit ruff.... I have been
looking at generic O2 Sensors. (Bosch/NGK).

So any help on which wire should be going where on the plug harness would
be greatly welcome.

Also, if anyone has done a generic O2 Sensor, advice would be nice.

Cheers

Run Back and Front HO2 (Lambda Sond)

Do one at a time, so you don't get your sensor mixed up.

 

Just an update, the front HO2 sensor, does not like cheap generic ones. Had to put a Walker OE replacement one $350AU
