What is bank 1 sensors location on ford contour

Bank 1 is where the number one cylinder/spark plug is located. If this is a 4 cylinder engine, number 1 is at the front of the motor and bank 1 is irrelevant and the number 1 sensor would be the one screwed into the exhaust manifold attatched to the cylinder head. If it is a 6 cylinder than number one is on the side closest to the radiator, and at the back of the engine near the exhaust crossover. The number 1 sensor is going to be the one screwed into the exhaust manifold just outside the cylinder head.
