Question about the Mercedes-Benz G 500

I’m about halfway through building this one. I’m curious does something connect here to allow you to control from the driver seat or do you operate this separately? I’m worried I might’ve missed something and it’s driving me crazy. I’m just about to start adding the backseats (Bag 8). TIA!
