An electrical harness assembly is provided that comprises a flexible printed circuit electrically connected to one end of an electrical connector. The other end of the electrical connector is presented for connection to another electrical component. Electrical tracks or conductors in the flexible printed circuit terminate in receiving holes. The electrical connector comprises terminals, each of which has a first end that is received in one of the receiving holes to form a connection formation, and a second end which is present for connection to the other electrical device. The connection formation is encapsulated so as to be sealed, thereby providing a reliable and robust connection between the connector and the flexible printed circuit.
