Apexi pen style turbo timer o2 wire???

[grdeclipse]

Hello fellow dsmer's I have a Apexi turbo timer (pen style). I have the harness that plugs into the ignition harness and I know where the e-brake wire (grey) and the ground wire (black) go. The only wire I don't know where to hook up is the white o2 wire. Does anybody have this turbo timer and if you do where did you tie in the white o2 wire? Or does it even have to be wired in? Is it just to read the A/F ratio or does it have something to do with calculating the proper amount of time to turn the car off? thank you for the advice and responses any input is greatly appreciated.

I didn't hook up that wire, its just for the integrated narrow-band feature of the turbo timer.

It doesn't have to be hooked up. If you do decide to use it, it should be Pin 4, which is a white.
