if its a narrow band then its quote easy to fit

should be 3-4 wires

1 - earth
2 - power
3 - ecu wire

1 - run this to a earth
2 - run this to a switched live ( so that it only works when the car is running)
3 - i bridges this onto a ECU wire at the ECU

see this piccy :

if its a wideband - then you need to change the 02 into a wideband one - and connect the wide band to one of the wires

So a somewhat related question, mainly relating to grinder's diagram, what's the input voltage range for a wideband that the stock ECU can read?

You mean output range for a wideband that the stock ECU can read?

Most widebands refer to it as "simulated narrowband". 0-1V. They quite literally simulate the peaky, non-linear output of a narrowband.

I read that its not convenient to change the o2 with a wideband one since its too hot there, not sure tho, still researching before i put mine in, but probably going to drill far below the downpipe to avoid condensated water (can crack the sensor apparently) and heat

It depends on the sensor. Some are more tolerant than others of heat. And it depends on the controller as well. Some blindly control the built in heater without compensating for exhaust heat.

All Innovates are massively intolerant of heat in my experience. Well, frankly, they are massively intolerant of nearly anything.

The Wolf AF-1 is designed for a LSM-11 (4-wire) narrowband O2 sensor. They call it a "wideband" because the LSM-11 has better resolution than non-heated (1-wire and 2-wire) sensors, but it isn't actually a wideband sensor as we would call it today. It will not work with a UEGO wideband sensor.

Condensation collects in the bottom of the pipe, so mount the O2 sensor near the top or side of the pipe. You will need to weld on a bung because the pipe is not thick enough to support threads.

You can install a heat sink if needed:

HBX-1
