Will this plug directly into my factory wiring harness?

Yes — this uses factory connectors and integrates with your existing mirror control switch. No splicing or relay work required.

Can I paint this before I install it?

Absolutely. The paintable housing is designed for prep and paint before mounting. Just mask off the motor housing and connector before sending it to the painter.

Do I need any fasteners to mount this, or are those included?

Mounting hardware is not included — you'll use your factory fastener points. Check your vehicle's mirror bracket before installation to confirm screw type and count.
