Method and system for displaying routing diagram with highlighted routable components

A method includes transmitting a request for a computer-readable routing diagram, such as a wiring diagram, a pneumatic or hydraulic line diagram, or an optical cable diagram. The method also includes receiving, in response to the request, a routing diagram including a connectable component and at least a portion of a routing set. The connectable component is associated with both a connectable component identifier and the routing set. The routing set contains one or more routable components, such as electrical circuits, pneumatic or hydraulic lines, or optical cables. Further, the method includes displaying, on a display, the routing diagram and at least the portion of the routing set highlighted. Displaying at least the portion of the routing set highlighted occurs in response to an occurrence of the connectable component being selected from the routing diagram displayed on the display or in response to the request including the connectable component identifier.
