Will this connect to my factory wiring harness without modification?

Yes—this mirror is built to OEM spec and plugs directly into your existing power-mirror connector. No splicing or adapter harness needed.

Does the power mechanism work the same way as the original?

Exactly the same. Driver controls directional tilt through the factory switch panel. If your car came with power mirrors, operation is identical to what you're used to.

What do I need to install this myself?

Basic hand tools and a trim removal kit. The mirror mounts at factory points—no drilling or custom brackets. Installation typically takes under 30 minutes per side. Refer to your service manual for torque specs on fasteners.
