Abstract
A vehicle antitheft system includes a housing that is supported by the vehicle's starting current power line between the vehicle's battery and the vehicle's starter motor. The starting current power line is cut, and one end of the line is advanced into an input channel that is established by an input bus bar in the housing. The other end of the line is advanced into an output channel that is established by an output bus bar in the housing. Plural MOSFETs are in electrical contact with the bus bars, and a control circuit controls the MOSFETs in response to a remotely generated rf enable signal. Consequently, the vehicle can be started by turning the ignition switch only after receipt of the enable signal. The starting current power line is held in the channels by set screws.
