A connector mating assurance system includes an audible sensor configured to be located in a vicinity of a mating zone for electrical connectors. The audible sensor is configured to detect an audible sound when the electrical connectors are mated. The system includes a connector identification sensor configured to be located in the vicinity of the electrical connectors. The connector identification sensor is configured to identify the presence of the electrical connectors. The system includes a controller connected to the audible sensor and the connector identification sensor. The controller receives connector identification signals from the connector identification sensor and the controller receives audio signals from the audible sensor. The controller processes the connector identification signals and the audio signals for mating assurance.
