1. A system comprising: a heater located within a steering wheel anda heater located within a vehicle seat;wherein the heater in the steering wheel is a first plate and the heater in the vehicle seat is a second plate and a shift in a signal is monitored between the first plate, the second plate, or both so that a presence and absence of an occupant is detected, andwherein the heater in the steering wheel and the heater in the vehicle seat are a sensor. 2. The system of claim 1, wherein the heater in the seat is grounded and the heater in the steering wheel is grounded when current is applied to the heater in the seat and the heater in the steering wheel. 3. The system of claim 1, wherein a switch is located between a power source and the steering wheel heater. 4. The system of claim 1, wherein a switch is located between a ground and the steering wheel heater. 5. The system of claim 2, wherein a switch is located between a power source and the steering wheel heater, and a switch is located between a ground and the steering wheel heater. 6. The system of claim 1, wherein the steering wheel heater is connected to a sensing system that detects a change in capacitance between the steering wheel heater and the vehicle seat heater. 7. The system of claim 1, wherein the steering wheel is connected to a sensing system that detects a change in voltage due to a presence of an occupant, contact of an occupant with the steering wheel, contact of an occupant with the vehicle seat, or both. 8. The system of claim 1, wherein a switch between a battery and the seat heater and a switch between a ground and the seat heater are off when a sensing current is applied to the system. 9. The system of claim 5, wherein a switch between a battery and the seat heater and a switch between a ground and the seat heater are off when a sensing current is applied to the system. 10. The system of claim 1, wherein the steering wheel heater is two discrete heater pieces and each piece individually receives the signal, energy, or both. 11. A method comprising: a) installing a heater into each of two discrete components of an automobile that are located adjacent to each other;b) providing energy to the heaters so that the heaters produces heat;c) providing a signal to the heaters so that a signal passes through the heaters to determine presence of an occupant, contact between the occupant and one or both of the two discrete components of the automobile, or both; andd) monitoring the signal for an occupant, lack of an occupant, lack of contact between one of the two discrete components and the occupant, or a combination thereof. 12. The method of claim 11, wherein the method includes a step of monitoring a shift in the signal between the combination heaters and sensors in the two discrete components. 13. The method of claim 11, wherein one of the two discrete components is a steering wheel. 14. The method of claim 11, wherein one of the two discrete components is a seat. 15. The method of claim 12, wherein one of the two discrete components is a steering wheel and one of the two discrete components is a seat. 16. The method of claim 11, wherein the energy provided to the combination heater and sensor is provided by a pulse width modulated technique. 17. The method of claim 11, wherein a switch is located between a power source and the heater in the steering wheel and the switch is closed when energy is provided to the heater and the switch is open when a sensing signal is applied to one or both of the heaters in the two discrete components. 18. The method of claim 11, wherein a switch is located between a ground and the heater in the steering wheel and the switch is closed when energy is provided to the heater and the switch is open when a sensing signal is applied to one or both of the heaters in the two discrete components. 19. The method of claim 14, wherein the method includes a step of closing the switch during application of energy and opening the switch during application of a signal. 20. The method of claim 15, wherein the method includes a step of closing the switch during application of energy and opening the switch during application of a signal.
