An electrical connector assembly is provided for terminating a plurality of electrical wires. A non-conductive connector housing mounts a plurality of signal terminals. A wire management module includes a non-conductive body mounting a plurality of ground terminals. The body positions a plurality of signal conductors and a plurality of ground conductors of the electrical wires, the ground conductors being terminated to the ground terminals. The ground terminals interengage with the connector housing to mount the wire management module to the housing with the signal wire conductors in position for termination to the signal terminals.
