Abstract: A connector for interconnecting a plurality of spaced electrical subassemblies in a motor-vehicle door has a basically rectangular flexible foil having a core part and formed with a plurality of strips extending from the part and carrying conductive paths. The strips are separable from one another and foldable to extend to the different subassemblies. The conductive strips and the core part are formed of a flexible and conductive material or of an insulating synthetic resin provided with the conductive paths. This core part has a plurality of different fields each provided with electronic circuit components, for instance a key-pad field, a decoding field, a processing field, an H-bridge field, and a transfer field. The circuit components can be passive or active, for instance whole integrated circuits can be mounted on the core part.
