Are you talking about the flap in the carpet? This is where the seat power lines come up from under the cabin floor. Raise the seat all the way and push your seat all the way back. You can get a better look under there then. It's safe to pull the flap up and look as well. There is a flap under the passenger seat as well. I ran the power for both my Rostra Lumbar supports through these flaps and into the center console area.
