Will this plug directly into my existing wiring harness?

The assembly includes electrical connectors designed for factory integration. Before ordering, confirm your vehicle's harness configuration matches — some trim levels have different connector types or additional features like heating elements.

Do I need to remove the old mirror or can I just swap the housings?

You'll need to remove the entire old mirror assembly from the mounting points. This mirror comes as a complete unit ready to bolt on — you're not transferring parts between housings.

What if the power adjustment doesn't work after installation?

Test the connection at the dashboard switch first — make sure power is reaching the mirror. If power is good but motors don't respond, the issue is likely the assembly itself, and a return can be processed without hassle. No installation damage needed to qualify.
