You can use the Routing Electrical Library Wizard
to create, edit, and import electrical cable and component data.You can edit the XML files used as libraries in electrical routing, and save the edited values in the existing library or in a new file.
A cable/wire library defines the attributes of the cables and wires, such as specification number, size, color, description, and so on. You need a cable/wire library if you want to assign electrical attributes to the route.
A component library cross-references the components in the from-to list to the SolidWorks part documents for those components. It also defines connector data for use when you create a harness drawing with the harness flattening and detailing functionality. (If you are not importing data with a from-to list and are not going to create a harness drawing, you do not need a component library.)
