Do these lights come with wiring harnesses or do I need to splice into my factory loom?

These are direct replacements that use your existing factory connectors — no wiring modifications needed. Unplug the old lights and plug these straight in.

Will these fit if my bumper has been modified or repaired?

Test-fit first. These mount at the factory signal light mounting points. If your bumper has been heavily cut or repositioned, you may need to verify alignment before final installation.

Can I return these if they don't look right once installed?

Contact ModSupply directly with photos of the fitment issue. Most fitment concerns are resolved on the first install, but reach out if something doesn't line up.
