Will this plug straight into my existing mirror wiring?

Yes. The heating element connects to your factory mirror harness — no rewiring needed. Just swap the glass and you're done.

Do I need to remove the entire mirror assembly to install this?

The glass lens swaps from the front. Access method depends on your specific mirror design — consult your service manual or test-fit first to confirm removal sequence.

What if the heater doesn't work after installation?

Check your factory mirror switch and fuse first — common cause is a blown fuse or switch issue unrelated to the glass. If the circuit checks out and heat still doesn't flow, the element may have been damaged in shipping. Document photos and contact our support team for warranty review.
