1. A system comprising: a first heater including a first plate coupled to a power source, wherein the first heater is configured to be located within a steering wheel;a second heater including a second plate coupled to the power source, wherein the second heater is configured to be located within a vehicle seat; andan input coupled to at least one of the first heater and the second heater, wherein the input is configured to provide a sensing signal to the at least one of the first heater and the second heater, wherein the sensing signal indicates a shift in capacitance between the first heater and the second heater, and wherein the shift in capacitance indicates whether a presence or an absence of an occupant is detected in a vehicle. 2. The system of claim 1, wherein the first heater and the second heater coupled to ground when current is provided to the first heater and the second heater from the power source. 3. The system of claim 2, further comprising a switch is located between the power source and the first heater. 4. The system of claim 2, further comprising a switch is located between ground and the first heater. 5. The system of claim 2, further comprising a first switch located between the power source and the first heater and a second switch located between ground and the first heater. 6. The system of claim 1, wherein the first heater is connected to a sensing system that detects, based on the sensing signal, the shift in capacitance between the first heater and the second heater. 7. The system of claim 1, wherein the first heater is connected to a sensing system that detects, based on the sensing signal, a change in voltage due to at least one of the presence of the occupant, contact of the occupant with the steering wheel, and contact of the occupant with the vehicle seat. 8. The system of claim 1, further comprising a first switch between the power source and the second heater and a second switch between ground and the second heater, wherein the first switch and the second switch are off when the sensing signal is applied to the system. 9. The system of claim 5, further comprising a third switch between the power source and the second heater and a fourth switch between ground and the seat second heater, wherein the third switch and the fourth switch are off when the sensing signal is applied to the system. 10. The system of claim 1, wherein the first heater includes two discrete heater pieces and each of the heater pieces is coupled to the power source. 11. A method comprising: a) installing first and second heaters heater into first and second discrete components, respectively, of a vehicle that are located adjacent to each other;b) providing current to the first and second heaters from a power source connected to each of the first and second heaters;c) providing a sensing signal to at least one of the first and second heaters so that the sensing signal passes through the at least one of the first and second heaters, wherein the sensing signal indicates a shift in capacitance between the first heater and the second heater; andd) determining, based on the sensing signal, at least one of presence of an occupant, lack of occupant, and lack of contact between one of the first and second discrete components and the occupant. 12. The method of claim 11, wherein the method includes monitoring a shift in the sensing signal and determining the at least one of the presence of the occupant, the lack of the occupant, and the lack of contact based on the shift. 13. The method of claim 11, wherein one of the first and second discrete components is a steering wheel. 14. The method of claim 11, wherein one of the first and second discrete components is a seat. 15. The method of claim 12, wherein the first and second discrete components correspond to a steering wheel and a seat, respectively. 16. The method of claim 11, wherein the current is provided in accordance with a pulse width modulated technique. 17. The method of claim 11, further comprising providing a switch between the power source and the first heater, wherein the switch is closed when the current is provided to the first heater and the switch is open when the sensing signal is applied to the at least one of the first and second heaters. 18. The method of claim 11, further comprising providing a switch between ground and the first heater, wherein the switch is closed when the current is provided to the first heater and the switch is open when the sensing signal is applied to the at least one of the first and second heaters.
