Flexible circuits are described including markings that indicate connections between their flat-wire conductors and specific circuits of a vehicle electrical system. Wire conductors within the flexible circuit share connections with different circuits of the vehicle electrical system. To indicate a connection between a wire conductor and a vehicle circuit, the flexible circuit includes one or more human or machine-readable marks specifically indicating the connection, in some cases, at a position where the connection is to be made. The marks can include etchings or printings on the wire conductors or printings on or otherwise visible from the insulating body that protects the wire conductors.
