Will this plug into my existing wiring harness?

This mirror is designed for factory mounting points, but electrical connector compatibility depends on your vehicle's original configuration. Verify the plug type matches your Civic's harness before installation—some adapters may be needed.

Does this come with the bracket hardware needed to mount it?

The assembly includes the mirror itself, but confirm all fasteners are present before beginning install. You may need additional hardware depending on your existing mount condition.

Can I use this as a direct replacement, or do I need to remove the old mirror first?

You'll need to remove your current mirror and disconnect its wiring. This unit mounts to the same factory points—no drilling or frame modification required—but take time to match the connector before fully securing it.
