Will this bolt straight into my factory housing?

Yes. This assembly mounts at factory points with no drilling or cutting required. Drop it in and wire it to your existing harness.

Do I need to splice wires or can I use the original connector?

Check your truck's connector type before ordering. If your factory harness uses a different plug style, you'll need an adapter or solder a new connector—neither is included.

Is there a warranty if the LED fails?

Warranty details are handled at checkout. Review the return policy for your region before purchase.
