Bank 2 is the one in the front near the radiator (cyl 2,4,6)
Bank 1, sensor 1 is the one near the firewall/oil filter (cyl 1,3,5)
Bank 1, sensor 2 is the one near the cat

This pic is for a cali spec, but you get the bank/sensor number idea - fed spec will look like this: http://www.courtesyparts.com/A32_O2-sensors.html
