An arrangement for indicating that an electrical connection is not established between first and second electrical circuit components includes a shorting contact which is disengaged upon first and second electrical connectors establishing a connection. As long as the shorting contact is engaged, current flows to an indicator lamp indicating that the first and second connectors are disengaged. This arrangement is utilized to notify the operator of a motor vehicle that a connector is disengaged from an air bag system diagnostic module and needs to be reconnected so that an igniter disposed within an air bag in the vehicle is connected to an inertia sensor which energizes the igniter in order to cause a gas expansion to inflate the air bag. When the connector is connected to the module, the lamp is not illuminated.
