Will these bolt straight into the factory mounting points?

Yes. These are designed for factory mounting locations — no drilling or modification required. You're working with the existing holes and brackets.

Do I need to splice wiring or can I use the original connectors?

Connector type is not specified. Test-fit before final installation to confirm whether you're reusing existing pigtails or running new wire. Many buyers use the factory harness if it's still intact.

Can these be painted or do they come ready to install?

These ship primer-ready. If your bumper or fender has been repainted, you may want to match the finish for a clean look — most shops can do this during your bumper respray.
