Do these connect to my factory wiring without modification?

Yes. These use factory connectors and bolt to the existing mounting points. No splicing, no relay modules, no additional wiring needed.

Will these fit my truck if it's a different year within the range?

Fitment is year-specific — confirm your exact model year before ordering. Check the Convermax YMM filter on this page to verify compatibility.

Do the bulbs come installed?

The lights ship as complete units. Verify bulb condition and function before final installation, and refer to your service manual if replacement is needed.
