electrical conductors especially electrical conductors for distributing power to electrical components in vehicles, commonly known as "wires" and "wire harnesses", electrical conductors for providing ignition power to spark plugs, commonly known as "ignition wires", and electrical conductors for connecting a vehicle battery to the vehicle power system, commonly known as "battery cables"; connectors for interconnecting electrical conductors; terminal posts upon which electrical connectors mount to provide and electrical interconnection between the item bearing the terminal and an electrical conductor, commonly known as "terminals"; and power distribution units where on or more electrical conductors terminate and are interconnected to other electrical items, commonly known as "junction boxes"
