Will these connect to my existing wiring, or do I need to run new harness?

The integrated switch ties into the factory fog light circuit if your vehicle has one. If wiring runs to the bumper area already, this assembly plugs in. If not, you'll need to route power from the fuse box — basic automotive wiring, nothing exotic.

Do the chrome bezels come pre-installed, or do I need to snap them on?

Bezels are included but not pre-mounted. You'll install the light assembly first, then secure the chrome ring around it for the finished look. Mounting method for the bezel itself is not specified — test-fit before committing to adhesive or fasteners.

Can I return these if they don't fit or work with my setup?

Contact our support team with photos of your vehicle's fog light mounting area and any error codes from the switch. They'll confirm compatibility before any returns are processed.
