Do these mount at the factory fog light locations?

Yes. These bolt directly to the factory mounting points on the steel bumper — no drilling or brackets needed. Test-fit before final install to confirm alignment.

Will I need to wire these myself?

You'll need to connect power and ground to your vehicle's electrical system. Wiring harness and connectors are not confirmed — check your truck's factory fog light wiring diagram or consult your service manual for proper gauge and routing.

Can I paint these or do they need any prep?

The clear lenses are not paintable — they're finished as-is. The housing may accept paint if desired, but no prep work is specified. Sand and prime according to your vehicle's paint process if customization is planned.
