A backshell for an electrical connector gives the electrical connector handedness to force a particular orientation of the connector with respect to a device in order to limit the choice of devices to which the electrical connector can be attached. The backshell fits around the connector and a portion of a cable connected to the connector. The cable is forced into a right angle turn in the interior of the backshell to give the device handedness.

A cable containment device for supportedly routing cables and air lines along a cross member of a truck frame to eliminate potential interference of the cables and air lines with operating structures beneath the cross member defines an elongate channel having at least a horizontal bottom wall which extends across a major portion of the length of the cross member for providing securely supported elevation of the cables above the operating structures.

A process for replacing a multi-functional original installed harness for a harness or cable for a mobile vehicle in a efficient and time saving manner. More specifically, the procedure involves: (i) identifying the critical electrically engaged components engaged to a multi-functional original installed harness for an engine that requires replacement; (ii) disconnecting the original installed electrical harness from only those critical components; (iii) running an electrical service overlay harness physically adjacent to the original harness; and (iv) engaging the critical components to the service overlay harness. This triage-like repair saves a significant amount of time and effort. The critical components for a vehicle are those in which an electrical fault in a circuit in the multi-functional original installed harness will result in the engine of the vehicle failing to start, failing to run, or will provide a service light or fault light to the driver in the cab of the vehicle indicating the need for immediate service.

A failure warning device is provided for use with an auxiliary pump unit made ready by either an ignition-on signal or a brake-on signal and activated by a pump-failure signal. The failure warning device has a monitor circuit coupled to a warning circuit. For maintaining reliability of the auxiliary pump unit, the module circuitry is wired as a monitor not including circuit components of the auxiliary pump unit. It has a first input coupled to a common ready signal produced by the pump unit and a second input coupled to a motor terminal of the pump unit. The monitor circuit responds to failure-related states of the ready signal and the motor terminal impedance and voltage by generating an anomaly signal. The alarm circuit switches on an alarm, such as a buzzer and light, when it receives both the ignition-on and anomaly signals. The monitor circuit can include a circuit for generating the anomaly signal when a comparator detects a difference between the brake-on signal and a simultaneously activated brake stop light signal. The monitor can also include a circuit to activate the alarm if a brake circuit detector senses a brake circuit failure.
