Do these headlights require new wiring or can I use the factory connector?

These are designed to use your factory headlight connectors. The LED DRL circuits integrate into the assembly, so you're working with OEM-style plugs—no custom harness needed.

Will these fit without removing the bumper or fender?

They mount at factory points inside the headlight bucket, so bumper removal isn't necessary. You'll access them from the engine bay side, same way you'd pull the OEM units.

Do the LED DRLs come on automatically with the ignition, or do I need a separate control module?

Your factory electrical system controls DRL behavior through the existing light module—no additional control box required. Wiring follows stock OEM logic once plugged in.
