Hope this helps

Bank two are the even cylinders. Follow exhaust manifold on the side. You will find an O2 sensor just after or on the manifold, before the catalytic converter. Then, look after the catalytic and you should find another O2 sensor, this is the one you mention in your post.

Sensor - Front Crash Removal
WARNING: Vehicle sensor orientation is critical for proper operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) is involved in a collision, inspect the sensor mounting bracket and wiring pigtail for deformation. Replace and properly position the sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed.
WARNING: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment.
WARNING: To reduce the risk of personal injury, do not use any memory saver devices.
NOTE: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE: Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic procedure again.

Engine compartment and center pillar post between both doors

From the F-150 Forums, since I just bought one and this worked!

This is straight from my 2009 f150 owners guide

Preperation
1. the parking brake is set
2. truck in park
3. ignition switch is in off position
4. both seat belts are unbuckled

Disable Belt-Minder
1. turn the ignition switch to the on position, DO NOT START THE ENGINE.
2. wait until the safety belt warning light turns off. (approximately 1 minute).
* step 3 must be completed within 50 secs after the safety belt warning light turns off.
3. buckle then unbuckle the seat belt nine times, ending in the seat belt unbuckled.
* after step 3 the restraint warning light, (airbag light) will turn on for three (3) seconds.
4. within approximately seven (7) seconds of the light turning off, buckle then unbuckle the safety belt.
* the restraint system warning light will flash four, (4) times per second for 3 seconds for confirmation

you can do this for the passenger side also!!!


*NOTE
in step 3. after three times buckling and unbuckling the restraint warning light lit up in my truck. SO I WENT TO THE NEXT STEP, (STEP 4). waited 3 seconds and i buckled and unbuckled.

in the buckle /unbuckle procedure do it some what slowly and watch for the light. it may not take 9 times.
