Default Wiring o2 sensor into ecu tgv

I was told I need to wire my o2 sensor into my ecu for tuning. Both the front and rear o2 sensors are hooked up. This is a third senor. Where do I connect it? Directly into the ecu? Splice it into a tgv wire because I have tgv delete? If so how? I feel like there should be a tutorial for this, thanks.

iwire makes a kit for this.
https://forums.nasioc.com/forums/sho...ghlight=tgv+o2 talks about doing it yourself.

One of the wideband 0-5v outputs to one of the tgv 0-5v inputs, then modify the logger definition to convert and read afr. Can use MAF input as well if you are speed density, 0-5v ethanol output goes to one of these inputs too
