The plug assembly includes a plurality of pins and a plurality of racks for selectively engaging the plurality of pins. Each rack of the plurality of racks has a first locking bar-receiving groove along a neutral axis and at least a second locking bar-receiving groove spaced from the neutral axis, wherein a spacing of the second locking bar-receiving groove from the neutral axis of a first rack of the plurality of racks is different from a spacing of the second locking bar-receiving groove from the neutral axis of at least one other of the plurality of racks.
