Run wideband o2 off of Aristo ECU..

I currently have the stock o2 sensor (3 wire) feeding the Aristo ECU and wanted to eliminate it and use my wideband o2 (Which is being used as purely a monitoring device right now) to feed it...

How do I make this work?

I am looking for as specific and detailed information as possible

is it as simple as just cutting off old o2 and taking the wires to wideband?

Do you know the part # for stock JDM 3 wire o2 sensor

The stock o2 sensor is most likely narrowband and the ecu is designed for a narrowband. Even if your ecu could read the wideband, it most likely won't run that great with it.

Does your wideband has a narrowband output?
If it does, then you would wire the narrowband output from your wideband into the wiring harness that connects to the ecu.

So it would go:

Wideband O2 sensor ----> Wideband computer----->Narrowband output wires ---->wiring harness--> ecu.
