Will I need to run new wiring, or does the switch harness plug into factory locations?

The included harness is designed for direct integration at factory locations. Route the harness along existing under-dash areas to keep it tucked away. Confirm routing path with your vehicle's manual to avoid heat sources or moving components.

Do the bulbs come installed, or do I need to source them separately?

Bulbs are not included. You'll need to get the correct bulb size for your specific model year before installation—check your owner's manual or contact support for the exact spec.

Can I install these myself with basic hand tools, or do I need a shop lift?

Factory mounting points are accessible from underneath the vehicle. You'll need basic sockets and a floor jack with jack stands. No cutting or welding. Most installs take under an hour once you've confirmed the mounting orientation.
