There are 2 O2 sensors on your Ford Ranger. There will be one a foot or two before the catalytic converter and one a foot or two after the converter. I don't have a diagram but you will only need to look for the identical sensor located up or downstream from the first one that you replaced.

B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter
