Lambda voltage / wiring / signal

I need to output my wideband to the ECU.

The lambda plug has 4 wires. 2 x white (heater), 1 x black (signal) and 1 x grey (ground).

What voltage or output should I use from the wideband? There are two options:

Analog output one is 0V =7.35 AFR and 5V = 22.39 AFR.
Analog output two is 1.1V = 14 AFR and .1V = 15 AFR.

I'd think it would be output 1?

which ecu? if its oem then you can only use the 0-1v input, any mappable ecu uses the 0-5v scale

Yes it's the stock Magnetti 3 plug. So output 2 then?
