Abstract: An appartus (10) attaching successive pairs of wires (12) to successive pairs of opposed contacts (15) of a connector (16) comprises a connector-carrying carriage (44,46) mounted for movement along a longitudinal axis. Each of a pair of ram assemblies (100) is mounted on opposite sides of the carriage for movement to and from a separate one of a pair of opposed contacts on the connector. Each pair of wire guides (58) is situated adjacent to a separate one of the ram assemblies for guiding a wire pulled thereacross into alignment with one of a pair the opposed connector contacts. Once each wire is aligned with the connector contact, each ram assembly is actuated to attach the wire to the contact. After wire attachment, an advancing mechanism (120, 126, 134, 142, 146) advances the carriage so that each of a successive pair of contacts is opposite a separate one of the ram assemblies.
