^ Exactly. Since you dont have Fog Lights on your Car, you do not have the Wiring Harness. When you purchase them they include the Wiring so you can run it yourself. You actually already have some wiring going from your Fuse Box to the Engine Bay. The OEM Fog Lights come with 2 Harnesses, the Engine Bay Harness and then the Underdash/Switch Harness.
The Block Off Plate is for the Fog Lights as stated by sk8shorty017, not for the Bumper Pole like deemee said. The Bumper Pole Switch goes in the Center Console/Armrest Plugs.
