An electrical connector assembly includes a first connector module including pins configured to be terminated to a circuit board and a second connector module including pins configured to be terminated to the circuit board. The electrical connector assembly also includes a carrier system including an organizer having openings therethrough in a predetermined pattern. The organizer is coupled to the first and second connector modules such that at least some of the pins of the first connector module extend through the openings of the organizer and such that at least some of the pins of the second connector module extend through the openings of the organizer. The first connector module, the second connector module and the organizer are configured to be mounted to the circuit board as a bundled unit.
