Will this plug directly into my factory wiring harness?

Yes—this is OEM specification, so it connects to the factory mirror harness without adapters or modifications. Confirm your vehicle's mirror harness is intact before installation.

Does the puddle light bulb come installed and functional?

The puddle light module is integrated into the mirror base. Test the light before final fitment to ensure the bulb and circuit are working.

What if the heating element or puddle light fails after I install it?

Review modsupply.com's return and warranty policy at checkout. Most OEM assemblies are covered within the standard return window if defects appear on arrival—not after installation.
