Do these bolt straight into the factory mounting points?

Yes. These mount at the factory cab light locations — no drilling or relocation needed. Just unbolt the old lights and bolt these in.

Will I need to run new wiring or splice into the factory harness?

Wiring configuration not specified — confirm your truck's cab light connector type before purchase to ensure compatibility with your electrical setup.

Do these come with everything I need to install them?

You're getting the pair of lights. Check your truck's factory fasteners and connector type before ordering to make sure you have what you need for a clean install.
