Will these bolt directly to my factory fog light mounting points?

These are engineered for Cascadia fitment, but confirm your current fog light bracket type before ordering. Factory mounting points vary by year and trim — test-fit or consult your service manual to verify bolt alignment.

Do these lights come with wiring harnesses and connectors?

The listing confirms the light assemblies only. You'll need to verify connector compatibility with your truck's existing fog light circuit or source an appropriate harness separately.

Can I run these on my stock electrical system without upgrades?

LED fog lights draw significantly less power than halogens, but your truck's wiring should handle the load. If you're upgrading from incandescent originals, you're in good shape. Have a tech double-check if you're unsure about your current circuit capacity.
