I know the a/f guage is useless but i got it as a present from my mother for my birthday and i cannot return it. So, i have decided to put it in my car for the time being and have give me a light show! HAHA. Anyway is there a easy way to hook this up to my 2004 WRX? Which o2 sensor do i hook it up to? Front or back? Which wire do i splice? Is there anyway to splice an o2 sensor wire at the ECU? Or do i have to splice it at the sensor itself? Any help would be appreciated!

Thanks,
Zach

Anyone know?

This has been brought up several times... if you do a search you find alot of info on this...
I tried to put one in my car and it does nothing,,, it just sits there on rich... not even a light show:furious: I taped into every wire that you can immagine and I got nada,,, for the WRX you need a wideband o2 sensor for it to work properly,,, I belive if you got to ravensblade.com
or do a search on this sight you should find the link,,, it has a diagram of the computer and what wires are what... hope this helps

Later On
