Abstract: A splicing head for positioning multiple wire pairs of a cable for connection to an electrical connector is provided with a removably mounted comb to facilitate the addition of a second cable to a connector with a connected first cable. The splicing head has a bed for receiving a modular electrical connector with its sattached cable. The comb is then mounted by vertical supports on a backside of the splicing head. The comb has multiple wire guides. A second cable is placed adjacent the comb and its wire pairs are separated and placed in the wire guides. The ends of the wires of the second cable are then attached to proper contacts on the modular connector mounted on the bed which already carry the corresponding wire pairs of the first cable. The comb is then removed to allow removal of a connected unit consisting of the modular connector, the pre-connected first cable, and the newly connected second cable.
