Will this headlight bolt straight to my factory harness and mounting bracket?

Yes. This is a direct replacement—it uses the same H13 connector and mounts at the factory attachment points. No wiring changes or bracket modification needed.

Do I need to do anything to the lens or housing before installation?

The black housing arrives ready to install. If you want to clean the lens after unpacking, use a soft cloth and mild soap. No prep, primer, or paint required.

Does this come with a bulb, or do I need to transfer mine from the old headlight?

Bulb not included—transfer your existing H13 bulb from the original headlight, or purchase a replacement bulb separately.
