A steering wheel heating assembly 10 which electively provides a relatively high voltage electrical signal to a heating element 16 which is coupled to a steering wheel, effective to heat the steering wheel. The assembly 10 includes a temperature sensor 28 which senses or monitors the temperature of the steering wheel and which communicates the monitored sensor to a controller 26. Should the temperature of the steering wheel be above a certain value, the controller 26 prevents the relatively high voltage signal from being communicated to the heating element 16. The controller 26 may also monitor the operating speed of the engine and prevent such signal communication when the engine is not being operated. The relatively high voltage signal allows a conventional clockspring wiring assembly 12 to be utilized since the power can be transferred at a lower current than would be required at a lower voltage, thereby obviating the need for a relatively costly and noisy slip ring assembly and relatively costly additional vehicular wiring.
