A connector assembly is provided. The connector assembly includes a connector having a connector body, and Tab-Down terminal, and a terminal position assurance device (TPA). The connector body has a cavity located therein and a flexible arm that is elastically deformable. The Tab-Down terminal is slidable in a first direction and in a second direction that generally opposes the first direction. The Tab-Down terminal is insertable within the cavity of the connector body in the first direction. The terminal position assurance (TPA) device is slidably engageable within the cavity of the connector. The TPA device has a primary lock support that is selectively positioned adjacent the flexible arm to limit deformation of the flexible arm. The connector assembly includes a pre-stage position and a full-stage position. In the pre-stage position the Tab-Down terminal moveable within the cavity. In the full-stage position movement of the Tab-Down terminal is limited.
