A connector position assurance device for a connector, said connector position assurance device comprising: a base portion having a top surface, a bottom surface, a base front end and a base back end; a pair of resiliently deformable beams (204, 205) extending from the front end of the base portion in a direction away from the back end of the base portion, the beams (204, 205) having free ends spaced from the base portion; a first beam of the pair of resiliently deformable beams (204, 205) having a first camming member provided proximate a free end of the first beam, the first beam having a first lockout projection engagement member provided proximate the free end of the first beam and in-line with the first camming member; a second beam of the pair of resiliently deformable beams (204, 205) having a second camming member provided proximate a free end of the second beam, the second beam having a second lockout projection engagement member provided proximate the free end of the second beam and in-line with the second camming member; a latch receiving cavity provided in the top surface of the base portion; positioning rails extending from the base portion, the positioning rails configured to cooperate with the connector to provide the proper positioning and stabilization to the connector position assurance device relative to the connector; wherein the positioning rails have latching projections, the latching projections configured to cooperate with the connector to prevent the removal of the connector position assurance device from the connector; wherein the latching projections are configured to retain the connector position assurance device in an initial position on the connector until the first camming member and the second camming member engage a mating connector to allow the first lockout projection engagement member and the second lockout projection engagement member to move past lockout projections of the connector. a base portion having a top surface, a bottom surface, a base front end and a base back end; a pair of resiliently deformable beams (204, 205) extending from the front end of the base portion in a direction away from the back end of the base portion, the beams (204, 205) having free ends spaced from the base portion; a first beam of the pair of resiliently deformable beams (204, 205) having a first camming member provided proximate a free end of the first beam, the first beam having a first lockout projection engagement member provided proximate the free end of the first beam and in-line with the first camming member; a second beam of the pair of resiliently deformable beams (204, 205) having a second camming member provided proximate a free end of the second beam, the second beam having a second lockout projection engagement member provided proximate the free end of the second beam and in-line with the second camming member; a latch receiving cavity provided in the top surface of the base portion; positioning rails extending from the base portion, the positioning rails configured to cooperate with the connector to provide the proper positioning and stabilization to the connector position assurance device relative to the connector; wherein the positioning rails have latching projections, the latching projections configured to cooperate with the connector to prevent the removal of the connector position assurance device from the connector; wherein the latching projections are configured to retain the connector position assurance device in an initial position on the connector until the first camming member and the second camming member engage a mating connector to allow the first lockout projection engagement member and the second lockout projection engagement member to move past lockout projections of the connector.
