A connector assembly can include a first housing, a second housing and a connector position assurance insert. The second housing can be configured to mate with the first housing in a mated configuration such that a first electrical terminal and a second electrical terminal are coupled. The connector position assurance insert can be coupled to the first and second housing in the mated configuration and can include a first flexible lock member at a first end and a second flexible lock member at a second end opposite the first end. In the mated configuration, the first flexible lock member mates with the first locking feature and the second flexible lock member mates with the second locking feature such that the first housing, the second housing and the connector position assurance insert are fixedly secured at an appropriate locked position.
