THESE VEHICLES MAY HAVE AN INCORRECT WIRING CONNECTION AT THE NUMBER TWO CIRCUIT BREAKER IN THE DRIVER'S CONTROL PANEL. THE MAIN FEED WIRE AND THE HORN RELAY-FLASHER FEED WIRE MAY HAVE BEEN CONNECTED IN REVERSE OF THEIR INTENDED POSITIONS. THIS COULD LEAD TO BREAKER CYCLING AND LOSS OF THE REAR DOOR BRAKE INTERLOCK FEATURE. THIS COULD RESULT IN INJURIES TO PASSENGERS IN THE DOOR IF THE BRAKE INTERLOCK FAILS TO PREVENT THE COACH FROM MOVING WHILE THE REAR DOOR IS OPEN.
