Based on the diagrams, there are two sensors. The upstream (89467B) and downstream (89475h ones both have 4 wires/connectors slots, which is consistent with narrow band. The sensors appear to be the same, other than specific mounting due to the difference in location.

I can't find any definitive info other than that.

Pondering some tuning?

Yes tks, trying to adjust the sensors to accept hydrogen fuel. It happens that the O2 might tell the sensors it’s lean when you want them thinking it’s rich so they’ll back of on the fuel. So need to have a way to adjust it to get the right mix,
