Step 1: Gain access to the back of the fog lamp location.
Step 2: Remove the existing fog lamp. Loosen the three screws behind the back support bracket and unplug the stock harness.

Secure the back mounting bracket onto your Ford F-Series truck via the top 2 silver holes and the bottom singular hole.
