A method and apparatus for making electrical harnesses of flat cable (30) terminated at respective opposite ends in electrical connectors (13) with individual conductors electrically connected to corresponding contacts of rows of contacts in conductor-receiving faces of the connectors (13). The flat cable (30) is fed longitudinally along a path extending towards a terminating station adjacent the feed path (12) along which the contact rows extend and a loop is formed in a leading end with the plane of the cable (30) and the loop axis extending perpendicularly to the contact rows and conductor-receiving faces. The leading and trailing ends of the cable loop are then rotated in opposite senses throug 90° to extend parallel to the plane of the conductor-receiving faces of the connectors (13) with individual conductors aligned with respective contacts and terminated therein. The apparatus includes a cable end slitting mechanism (35), eye forming mechanism (32), loop forming mechanism (37) and transfer mechanism (39).
