Will this work if my fog lights aren't currently wired?

This switch controls existing fog light wiring only. If your vehicle doesn't have fog lights installed, you'll need both the lights and their harness in place for this switch to function.

Do I need to remove the dash to install this?

Mount location varies by trim and dash configuration. Test-fit before committing to adhesive or fasteners to confirm clearance and access point for your specific vehicle.

What if the switch doesn't work after I plug it in?

Verify the fog light bulbs are present and the wiring harness is connected. Check your owner's manual for any inline fuses related to fog light circuits, as a blown fuse will prevent operation.
