Will this work with the factory wiring harness?

This light is a direct replacement, so it connects to the existing cab light wiring without splicing or modifications. Plug-and-play installation.

Do I need to remove the headliner to install this?

Installation method depends on your cab light design. Test-fit first to confirm access—most owner installations don't require headliner removal, but your truck's layout may vary. Refer to the OEM service manual for detailed steps.

Can I return this if the fit doesn't work?

Returns are handled through standard modsupply.com policy. Confirm fitment with your vehicle's cab light configuration before final purchase if you're unsure about compatibility.
