Will this mirror work with my existing door panel connectors?

This assembly is designed for factory mounting points on your door—electrical connections match OEM harness routing. Verify your door loom before final installation to confirm alignment with the power and heating connectors.

Does the heating element need a separate switch or relay?

The heating function integrates into the mirror assembly itself. How it ties to your vehicle's electrical system depends on your Focus's original wiring—some models run heat through the power window circuit, others through dedicated rear-window defrost logic. Check your wiring diagram or have a tech confirm before routing power.

What condition is this mirror in—new, refurbished, or salvage?

This is a new assembly. No core charge, no core return required—it ships ready to install.
