Adding reverse sensors?

[Reduxalicious]

As the title suggests does anyone know if down the line it would be easy to add the reverse sensor that beeps at you, I already have the hookups it seems they're just blanked off instead of housing the sensor.
I imagine it would require programming though.

I’m sure it can be done with new trim a software flash and the sensors themselves. It would probably be around $250-$300 for the trim and sensors. And who knows what they’ll charge you for the flash and install, my guess would be another $250 at least.
