Yeah most trucks didn't have the middle speaker wired up. Should be easy enough to run wires and put one in there though. How it is wired up depends on your stereo. You may contact the place where you bought the stereo from and ask them which wiring setup would give you the best sound. Since most stereos are set up for left and right, not many have a wire for the center. You may just hook up the center speaker with either the left or right dash speaker.
