Abstract: A connector assembly comprising a cap member having a plurality of fixed cap terminal position assurance mechanisms defined thereon, and a plug member having one or more of fixed plug terminal position assurance mechanisms defined thereon, wherein each of the cap terminal position assurance mechanisms fixably mate with each of the plug terminal position assurance mechanisms, wherein each of the cap and plug terminal position assurance mechanisms comprise a post projecting outwardly from each of the cap member and the plug member, and a cutout configured to fixably mate to the post. The cutout maybe configured adjacent the post, wherein the cap/plug terminal position assurance mechanisms are arranged proximate an outer rim of the cap/plug member or the cap/plug terminal assurance mechanism may be located generally in the center of the interface manifold.
