if you are looking at a 1999 cougar there are 4, 2 in the front exaust manifold and 2 in the rear, sensor two bank one is the bottom front sensor one bank one is the top front for the rear it is the same but it will be bank two. for other cars bank one is the side of the engine that has cylinder #one & bank two has cylinder #2 . sensor #1 is before the cat & sensor #2 is after.careful some cars like the 1999 cougar have a cat in each exaust manifold
