Defi afr guage with bosch wideband o2 sensor
 

I have a defi afr guage but it didn't come with a sensor. now in the "instructions" it says it can be used with a wideband or narrowband o2 sensor so I bought a bosch wideband sensor that I had intended to use. However i'm not sure if I need a wideband controller and I can't find a wiring diagram for the 5 wire sensor.

What gauge part number? Can you post a link to its documentation?
