The tail lamps need to be 3 wire style lamps. One for ground, one for brake, and one for running. If they are simple 2 wire lamps, then you need to replace them with the appropriate 3 wire lamps.
Your license plate lamp is wired into the reverse light circuit, and needs to be wired into the running lamp circuit.
All about that unibody life.
