I was told by dealer and chrysler that this is only on the 3500 ram . the seat belt warning light and the air bar light does not give any warnings when passenger person sits in the seat. that no chime will notify if seat belt is unhook only in passenger seat. i can't even put this part in my vehicle because no # for it. this to me is a safety item that should be in vehicle. the driver seat works ok just the passenger seat.
