Abstract: A wiring system for a vehicle instrument panel, which includes a plurality of electronic subassembly components electrically connected to at least one wire, is encapsulated in a plurality of troughs located to the rear of the instrument panel. The troughs extend between the subassembly components, Each trough has a finite length in at least one axial direction with an open side extending substantially along the length, so that the at least one wire may be received within the trough. The at least one wire is connected to at least one of the subassembly components. Wire restraints restrain the wire within at least one trough.

Abstract: A wiring system for a vehicle instrument panel, which includes a plurality of electronic subassembly components electrically connected to at least one wire, is encapsulated in a reconfigured ventilation duct structure located to the rear of the instrument panel. The ventilation duct structure, which extends between the subassembly components, is reconfigured to have at least one trough formed in it. The at least one trough has a finite length in at least one axial direction with an open side extending substantially along the length, so that the at least one wire may be received within the trough. The at least one wire is connected to at least one of the subassembly components. Wire restraints restrain the wire within the at least one trough.
