i need help. im trying to splice the o2 sensor on the ECU. which wire is it or where can i find the diagram to find out?

thanks

 

I'd recommend stopping where you are with that.

Just slicing an air:fuel ratio gauge into your stock narrow-band oxygen sensor signal, won't do any good (Other than giving you a cool light to look at). Get a wide-band oxygen sensor setup, that will give you PRECISE readings.

They're not expensive, as a matter of fact, I can sell you an AEM unit for $208.

 

yeah i stopped already.

 

truth

 

The AEM unit is nice and I use one instead of the secondary O2.
Helps with tuning and to make sure things are still OK afterwards.

 

i hear the ngk one is really good as well? anyone used or using it?
