Seat Warmers??

Seat warmers haha. Like stated above it is for the seat belt interlock that would not allow you to start the car with out buckling your seat belt. Quickly people found out that if they reached under the seat and unplugged the connector it rendered the whole set up useless. There will also be a small box on the back top passenger side of your engine firewall that could be used by a mechanic to start your car without having to be in the car with a seat belt on.
