Air Fuel Wire?

[CAPESR20DET]

I have a sr20det black top and I was woundering which wire do I tap into for my air fuel meter I have a white and 2 black wire.
Thanks

i would reccomend tapping into the garbage can as they are useless without a wideband, but they tap in to the o2.

Tap into the 02 sensor wire at the ecu. Its a white wire at pin 19. It's fairly easy if you go to radioshack and pick up a wire tap. Hook it up and you now have a dancing led light show. http://sr20det.nismo.org/ecuplug2.jpg
