Hit the turn signals... and the appropriate half of the bar flashes accordingly. And of course, turn on the hazards and it all blinks. Installation is a breeze. As for the electrical connection, that is as easy as plugging it into the factory 4 prong trailer wiring connection on the back of your vehicle. Don't have a trailer plug?
