A method of manufacturing a cable connector assembly including the steps of: connecting a mating member to a cable through an internal printed circuit board; enclosing a shell over the mating member and the cable; fixing a number of dowel pins to the shell; molding a strain relief over the shell; removing the dowel pins to form a number of pinholes in the strain relief; and telescoping an outer over-mold on the strain relief along a front-to-back direction.
