In general terms, the narrow band “gauge” is meant to be connected to a normal 02 sensor that gives out a voltage over a 1 volt range (0-1 v). That range is centered on target.

A wideband work on 0-5 V range output by a true wideband sensor. In most cases, the wideband system comes with it’s own 02 sensor desgined to work with the gauge.

Add some confusion that a wideband can output (simulate) a narrow band signal and that some of the narrow band gauges can be connected to OE\<M WB sensors. Effectively, I would buy one without knowing what model / style it is.
