Will this fit directly into my tailgate without drilling or cutting?

Yes. This assembly mounts at factory points — no modification to the tailgate needed. Verify fitment position before final fastening.

What wiring connection does this use?

Mounting method and connector type are not specified in the product details. Have your service manual or a wiring diagram ready during installation to match the correct harness.

Does the LED light source come installed or do I need to source a bulb?

The LED array is built into the assembly — no separate bulb needed. Once mounted and wired, it's ready to function.
