Do I need to modify wiring or the dashboard to install the switch?

The switch mounts at the factory location and ties into the existing fog light circuit. You'll need basic hand tools and a socket set—no cutting or custom drilling required if you're replacing OEM fogs.

Will these work with my vehicle's existing fog light wiring?

These are designed as a direct replacement assembly. If your van came with factory fog lights, the connectors and harness will match. If it didn't come with fogs originally, you'll need to run a harness from the battery and fuse box to the switch location.

Can I repaint or tint the smoke bezels a different color?

The bezels come with a smoke finish applied. They can be sanded and reprainted if you want a different look—use standard automotive primer and paint prep methods on plastic.
