An electrical connector assembly for terminating first and second electrical wires, the electrical connector assembly comprising a housing including a compartment for receiving first and second IDC elements and a cap movably mounted to the housing to cover the compartment. The cap is movable between an open position and a closed position. The cap includes a general body portion, a wire retention portion, and a latching mechanism. The wire retention portion includes first and second wire holders to retain and align the respective electrical wires within the housing for engagement with a gripping portion of the respective IDC element when the cap is placed in a closed position. The gripping force of the wire holders is less than a gripping force of the IDC elements. The latching mechanism can releasably fasten the cap to the housing when the cap is placed in a closed position. When the cap is returned to an open position after the cap was placed in the closed position, the first and second wires are retained by the first and second IDC elements and the first and second wire holders disengage the first and second wires from the cap.
