Will this mirror plug directly into my factory wiring?

Yes. This uses OEM connectors that match your vehicle's mirror harness. No splicing or adapters required.

Does the heater element draw power separately, or does it use my existing climate system?

It integrates with your factory climate system. When you activate your defrost or heated mirrors through the cabin controls, the element engages—no extra modules or independent switches to install.

What tools do I need to swap this out?

Basic hand tools and a socket set. You'll likely need to remove interior trim panels to access the mounting bolts. A service manual for your specific year will walk you through panel removal sequences.
