Will this plug directly into my truck's factory wiring?

Yes, this assembly uses the OE connector and mounting points — no wiring modification required. Bolt it in and you're done.

Is the bulb included, or do I need to transfer mine from the old headlight?

Transfer your existing bulb from the old assembly into this housing. The bulb socket is standard and accepts any H11 or compatible bulb for your model year.
