Do these bolt directly into my factory mounting points?

Yes. These mount at the factory rocker and lower fascia points — no drilling or fabrication required. Hand tools are all you need for installation.

What's the difference between amber and clear fog lights?

Amber lenses filter shorter blue wavelengths that scatter in fog and rain, reducing glare and improving contrast. Clear lenses let more light through but create more scatter in wet conditions. Amber is the better choice for actual fog and snow driving.

Will these work with the factory wiring harness?

These are designed as direct replacements and use factory connector geometry. If your truck came with fog lights, the harness and switch are ready to go. If it didn't, you'll need to run wiring from the battery or fuse box — a weekend DIY job.
