Do these plug directly into the factory wiring harness?

These mount at the factory fog light points, but connector compatibility depends on your truck's year and trim. Test-fit before you commit—some may need a pigtail adapter or splice, others plug straight in. Check your truck's current connector type first.

Will the black housing look right next to the rest of my bumper if it's a different color?

Black housings work on most F-150 bumpers, but if your bumper is body-color or a contrasting shade, the black surround will stand out. Paint the housing to match if blending is a priority.

Are bulbs and wiring harnesses included, or do I need to source those separately?

The fog light assemblies ship as units. Confirm what's inside your box before ordering—some buyers source additional harness adapters or relay kits depending on their truck's wiring setup.
