A connector assembly having a first connector housing, a second connector housing and a connector position assurance (CPA) member that is slidably mounted on the first connector housing for movement between first and second CPA positions. When the CPA member is in the first CPA position and the first connector housing is not fully mated to the second connector housing, the CPA member engages the first connector housing to inhibit sliding movement toward the second CPA position. Fully mating the first and second connector housings together unlocks the CPA member to permit it to be slid to the second CPA position to engage the second connector housing.
