Will these bolt straight into my factory mounting points?

Yes—these mirrors use the existing Super Duty attachment points with no drilling or frame modification needed. Install is plug-and-play if you're comfortable removing the old mirrors and connecting the power harness.

Do the LED lights tie into the factory wiring or do I need a standalone harness?

The LED lights integrate into the mirror assembly and route through the power harness. Your truck's factory electrical will support the load—no auxiliary relay or battery isolator required.

Can I use the heated glass and LED lights independently, or do they operate together?

Both functions are independent. Flip the heated glass switch on or off separately from your marker light circuit. You control each feature when you need it.
