Will this work with my factory mirror housing?

Yes — this is an OE-style lens designed to fit directly into the existing right mirror assembly. No modifications to the housing itself are required.

Do I need any special wiring or does it plug into the existing harness?

The heating element connects through the factory electrical connections in your mirror assembly. Your vehicle's existing heated mirror wiring harness will power it — no new wires needed.

What if the glass doesn't fit or I change my mind?

Inspect the glass and mounting tabs immediately upon arrival. If fitment issues arise, contact customer service with photos before installation — heated glass typically cannot be returned once mounted.
