An electrical connector assembly includes an electrical connector that defines a terminal cavity. The terminal cavity extends from an insertion opening to a mating opening. An inner housing is positioned in the terminal cavity. The inner housing defines an inner cavity. The inner cavity extends from an inner insertion opening to an inner mating opening. The inner mating opening is adjacent to the mating opening of the electrical connector. An electrical terminal is positioned in the inner cavity. A mating portion of the electrical terminal is adjacent the inner mating opening.
