Do I need to pull my dashboard apart to install the switch?

The switch mounts at the factory location and connects into the existing wiring harness. You won't need to disassemble the dash; it's designed to drop in at the stock switch location.

Will these lights work with my factory electrical system, or do I need a relay?

They tie directly into the OEM connector, so the factory system handles the load. No relay, no rewiring—plug the harness and you're done.

What if the bezel doesn't fit flush with my bumper?

Test-fit before final installation. The bezel is designed for your model year, but gap shims or minor trim may be needed depending on bumper condition. Verify alignment before committing fasteners.
