o2 sensor "bank2 sensor1"

I have a 97 firebird with a 3.8L V6. does anyone know which 1 of the 4 O2 sensors is the one called "bank 2 sensor 1"?

Before cat passenger side. At least it would be on the V8.

"bank 2" = bank with cyl 2 on it (pass side)
"Sensor 1" = first sensor

Thanks Mr. Luos

I called the dealer and that is where they said it was also.
