An electrical connection assembly provides an electrical connection for an electrical component mounted on a movable bed of a vehicle. The electrical connection assembly includes a sub-assembly supported on the movable bed, and another sub-assembly supported on the frame of the vehicle so that the two sub-assemblies make electrical contact when the bed is in one positions. The electrical contact can be broken when the bed moves relative to the vehicle frame. In one embodiment, both sub-assemblies are biased toward each other to maintain a solid electrically conductive path between conductive contacts on each sub-assembly. One sub-assembly can include a number of conductive plates, while the other can include a like number of conductive plungers. The conductive components are supported on insulator plates. One of the plates defines a plunger bore to receive a plunger therein such that the plunger can reciprocate and pivot angularly relative to the plate. A spring can be disposed within the bore to bias the plunger outwardly from the bore. The plunger can include an enlarged head having a chamfer to accommodate angular orientations of the plunger relative to the insulator plate.
