Will these plug directly into my factory wiring, or do I need a new harness?

These mount to factory points and use the included switch, but confirm your vehicle has the pre-wired fog light cavity before ordering. If wiring was never run to that location, you'll need to run harness yourself or have a shop do it.

Do I need to remove the bumper to install these?

Installation typically requires bumper removal for full access to mounting points. Plan 30–60 minutes depending on your comfort level and tools on hand.

Can I return these if they don't fit or I change my mind?

Contact ModSupply customer service for return eligibility. Fog lights are generally returnable within the standard window if unopened; installed units are non-returnable.
