Do these mirrors plug directly into the factory wiring harness?

These are designed to work with your truck's existing mirror harness. Test-fit and verify connector compatibility before final install — mirror electrical connectors can vary by trim and production year.

Do I need to remove or reprogram anything on the dashboard to activate the heater?

The heating function typically uses your truck's standard rear-defrost button. No programming or module swaps are required — it'll work like the factory setup once mounted and wired.

What if the spotter mirror is damaged during install or arrives defective?

Check your product receipt for the return window — ModSupply handles all claims within that timeframe. Damage during install is usually not covered, so handle the spotter lens carefully during removal and mounting.
