inductors active components or the like in a particular embodiment the load 68 can be a device that can be sensed by the controller 88 through the sensor 84 although a resistor will be used as an example other components can be used depending on what signal is used to actuate the actuator 56 for example any component or circuit that can induce a measureable difference when the plug 62 and receptacle 74 are connected can be used as the load 68 in an embodiment a thermal device 78 can be disposed in the receptacle 74 the thermal device 78 can be configured to have an electrical parameter that changes based on temperature for example the thermal device 78 can be a thermistor in another example the thermal device 78 can be a resettable fuse or polymeric positive temperature coefficient device in these examples as temperature changes a resistance of the thermal device 78 changes in an embodiment the controller 88 can be coupled to a power sensor 80 an actuator 82 and a sensor 84 the power sensor 80 can be configured to sense if power is supplied through the receptacle 74 the actuator 82 can be configured to actuate the actuator 56 the actuator 82 can also be configured to apply a stimulus bias or the like to the conductor 86 the sensor 84 can be configured to sense a voltage on the conductor 86 however in other embodiments the sensor 84 can be configured to sense a current supplied to the conductor 86 as illustrated the actuator 56 and vehicle share a common ground represented by conductor 68 however in another embodiment a terminal of the actuator 56 need not include ground for example the actuator 56 can be drive differentially the load 64.
