Do these mount at factory locations, or do I need to cut the bumper?

These use the factory mounting points—no cutting required. The housings slide into the existing fog light openings on the bumper cover.

Does the switch wiring run to the dash or hardwire to the battery?

The harness includes a dash-mounted switch. Route the main power lead through the engine bay and firewall to your battery or fuse box; exact routing depends on your vehicle's layout and electrical setup.

Can I return or exchange these if they don't fit my specific year?

Fitment is vehicle-year specific. Confirm your exact model year before purchasing. Contact ModSupply directly with photos or serial numbers if fitment concerns arise after arrival.
