Have just bought a universal sensor for my 93wrx, my oem sensor has red,black & white wires, the one I have just bought is a 4 wire one and has 2 white,grey and black....after searching on here I know the grey one goes to earth, am I right in thinking that the black goes to black and the 2 white go to white and red????


Or have I got completely the wrong sensor!!!

 

You have the wrong sensor, you need 3 wire one.
Where did you get it from?
Should try southern exhausts as do them for any make/model.

Got one for my old bmw e36 and cost £39.

Fitted a four wire to replace the three wire on mine a couple of years ago. Only difference is the earth is fourth wire and works OK.

 

Blimey what page did you find this post on!!! I did get the right sensor and checked before I bought it, just wasn't sure on the correct wiring, it's all done now, jobs a gooden!
