did the instruction sheet come with it? If not, you should be able to go to their website and get the install instructions.

Yes it did Kuch!, I can install it the only thing that I don't know is where to plug it so it can send signal to the ecu.

Gotcha, I believe it is pin 29 at the ECU that is used for the factory sensor. Are you hooking up a PIMPx or something?

Every WBO2 I have seen in the last few years has a narrow band O2 emulator output (0 to 1 V) that you can use as an input to the stock PCM that is looking for a narrow band signal. Without digging out my wiring diagrams I am pretty sure Kuch is correct that pin 29 is the stock narrow band O2 input to the TC EEC IV series of PCMs (LA, LA2, LA3, 8UA, etc). If the wire you are talking about is the NBO2 emulator output, connect it to pin 29.

If you are simply running the wideband as a standalone gauge to monitor your AFR, then simply leave it disconnected, tape it off and tuck it out of the way. I have an autometer wideband and it also has a similar wire as your innovate, I never connected it and don't need it until I hook up my PIMPx this summer.

^^^ Agreed. I still run the stock LA3 and just use my Innovate wideband to monitor the A/F ratio. The wideband really helped in tuning my home made meth injection system. I just securely taped the narrow band emulator wire out of the way.
