An electrical connector includes a first connector housing which is configured to cooperate with a second connector housing in a mated position to facilitate making an electrical connection. A connector position assurance device (CPA) is configured to cooperate with the first connector housing in a first position to allow engagement and disengagement of the first and second connector housings. The CPA has a second position which inhibits disengagement of the first and second connector housings from the mated position. The CPA also includes a locking feature configured to engage the first connector housing to inhibit unseating of the CPA. The CPA also includes a release mechanism which is operable from outside the first connector housing, and allows the locking feature to be disengaged from the first connector housing to facilitate unseating of the CPA.
