Does this plug into the factory wiring harness?

Yes — this mirror uses factory mounting and electrical connections. Plug it in where the original mirror connects; no rewiring needed.

Will the power and heat functions work right away?

They'll work immediately once the mirror is installed and connected to your vehicle's electrical system. Test both functions before finalizing installation.

What if the heating or power doesn't work after I install it?

Check your vehicle's fuse box first — a blown fuse is the most common cause. If the fuse is good and functions still don't work, the mirror assembly may be defective; contact support with your order number.
