An electrical connector assembling machine includes a connector strip feed unit including a feeding device configured to index the connector strip through a feed track in successive feed strokes and a contact loading assembly loading contacts into the connector strip. The contact loading assembly includes a wire distribution unit and a wire feed unit having a feeding device configured to simultaneously index wires through feed tracks in successive feed strokes. The wire feed unit includes a wire guide assembly guiding the wires through the wire feed unit. The contact loading assembly includes a contact forming unit and a contact loading device loading the contacts made from the wires into the connector strip as the connector strip is advanced through the electrical connector assembling machine.
