Do I need new mounting bolts or hardware to install this?

The assembly uses factory mounting points. Bring fasteners to match your vehicle's door panel — most builders source these from the original door frame or a hardware kit for your application.

Will this work with my existing door wiring and switches?

This assembly connects directly to factory wiring harness and button switches. No adapter harnesses or rewiring required if the connectors match your door loom.

What should I do before installing this in my door panel?

Test the motor and regulator operation on a bench before closing up the door. Connect it temporarily to battery power and cycle the window up and down to verify smooth movement and switch response.
