An electrical connector utilizing a plurality of terminals to which wires have been ultrasonically welded, most preferably via UWTI technology, wherein the terminals are aligned for the welding process and also aligned in the connector via one or more terminal carriers. Terminals are placed into respective seats in two terminal carriers, and wires are then ultrasonically welded to the terminals. The terminal carriers are then superposed and placed into a connector body of the electrical connector. The ultrasonic welding process is implemented by an anvil passing through an aperture in the terminal carriers at each terminal so that it is able to sonically and pressurably co-act with the tip of the ultrasonic welding apparatus to thereby effect an ultrasonic weld of the wire(s) to the respective terminals, preferably through the insulation thereof.
