It'* a pretty safe bet (99%) to say narrowband, especially on a vehicle like this from 95.
Wideband 02 are generally only aftermarket for fuel/boost controllers if i'm not mistaken, although some newer cars may come with them OE.

If you have a narrow band O2, an air fuel gauge is pretty useless. The range that the sensor tolerates as 14.7:1 is so narrow that your air fuel gauge is pretty much either going to be pegged rich or pegged lean at anything other than cruise conditions. You'd be better off adding an auxiliary wideband O2 (find a factory app. that uses a wideband and find a sensor on ebay). A factory narrow band sensor is designed to switch lean/rich only to achieve 14.7 to keep the catalyst happy. It really won't tell you that much about your tune.
