An exemplary embodiment of the invention relates to a method, system, and storage medium for providing a dynamic multi-dimensional commodity modeling process. The multi-conductor cable is of a length to extend substantially the length of the chassis, to carry various communication functions between the cab and a distal end of the chassis. Means for tightening the raceway include at least one guide member passing through the raceway to let a part of the elongate element slide freely transversely to the raceway, in front of the front edge of the raceway, elastically extensible means arranged along the elongate element, and securing means to connect at least one end of the elongate element to the front element. The conductive traces can be attached to the conductive traces over the shock-absorbing layer.
