I've seen the top pin broke out of that small board too many times. I guess it gets hit when the panel is going in/out of the dash. I recently saw a cure for it too. The original connector had the wires cut and a pig tail from a trailer harness added on. That moves the service disconnect to a remote location so the factory connector never needs pulled off the board pins again. Any 3 wire connector could be used. The trailer hitch connectors were a nice choice though since it has a similar appearence.
