Moot,
Like CVM said. If the wiring is on the blank on the left, it would turn off, temporarily, the beeping sound, if the rear sensors had detected something (like if you were backing up with a trailer etc). It would automatically reset next time you turned on the ignition. If you don't have the rear sensors, don't know if they are actually connected to anything or if it was just cheaper to make all the dash areas similar.
You can put your own type / color of switch in one of those blanks, to control whatever you want. Doesn't have to be a factory switch. I have a round, green illuminated switch in the one above my heated mirror control (to control the rear fog lamp).
