An electrical connector assembly includes a connector housing defining a cavity in which at least two electrical terminals are interconnected. The connector housing defines an opening configured to receive a cover that is configured to protect the at least two electrical terminals and thermally manage heat within the cavity. The connector housing may be configured to receive one cover configuration of a plurality of different cover configurations. A first cover configuration in the plurality of different cover configurations provides different mechanism to thermally manage heat within the cavity electrical connector assembly than a second cover configuration in this plurality of different cover configurations.
