Want to start mapping my Emanage Ultimate, but need wideband AFR sensor.

I have a spare (old) OEM sensor that I replaced a while back, because I thought it was malfunction, but didn't change a thing....

Subaru part number 22641AA080
found on the Internet that it is a BOSCH 0258007084.
It's got 5 wires (black, white, gray, yellow and red)

Is this a wideband ? Can I wire it into my Emanage Ultimate ?

Found another piece of information on my ECU pinout sheet

1 wire for sensor heater function (to ECU connector B134)

4 wires for AF signal (to ECU connector B136)
1 signal between 2.8 - 3.2v
1 signal between 2.4 - 2.7v
2 signals between 0.2 - 4.9v

with this info, can anyone tell if this is def. a wideband (0.2 -> 4.9v ?),
and how to connect it to my Emanage Ultimate ? :stupid:
Going with a local group buy on a PLX SM-AFR with new Bosch sensor
