An apparatus having an automobile engine block heater installed on a vehicle where the automobile engine block heater is automatically activated when the vehicle is properly positioned within a frame assembly. The apparatus includes at least two magnetic electrical adapters, one of which is mounted to the front of the vehicle and the other is mounted to the frame assembly. In one embodiment, the frame assembly includes an upright portion and a lower portion that lies flat on the floor. The upright portion secures the second magnetic electrical adapter that mates to the adapter on the front of the car. The upright portion is adjustable to match the height of the front of the car. Similarly, the lower portion includes a wheel well that receives a front vehicle wheel and is adjustable to match the length of the front end of the vehicle. The wheel well stops the vehicle when it is positioned properly, permitting the magnetic electrical adapters to mate. In a preferred embodiment, the apparatus also includes a status indicator designed to energize when the vehicle is properly positioned relative to the frame assembly. The upper portion is pivotably mounted to the lower portion to provide lateral range of motion in case the car overruns the wheel well. Conversely, a stop is used to disengage the magnetic electrical adapters when the car is backed away from the frame assembly.
