Do these come with wiring harness connectors?

The listing doesn't confirm connector type or harness inclusion. Check your OEM connectors before ordering — you may need an adapter or plug-and-play connector depending on your vehicle's existing wiring setup.

Will these work as a direct bolt-on replacement?

They mount at the factory fender position, so installation is straightforward. Test-fit before finalizing to confirm clearance and alignment with your body lines.

Can I use these with my factory electrical system?

LED markers typically draw less current than incandescent units. Your factory wiring should handle the draw, but if you're replacing OEM incandescent markers, the system will work without issues.
