Do I need to splice wires into the existing mirror harness?

The mirror is a powered unit, so electrical connection to the vehicle's power window/mirror switch is required. The factory harness on these trucks runs to the driver's door panel—you'll need to verify your existing connector matches before installation.

Will this bolt straight to my vehicle without drilling?

Yes—these mount at factory rocker points with no additional drilling or modification needed. Use the existing mounting holes on your door.

Is the mirror glass included?

Only the powered mirror assembly is included. If you need replacement glass, source it separately based on your specific condition and preference.
