A control module for an electrical stimulation system includes a connector assembly coupled to a sealed housing. A lead-assembly port is defined along a first end of the connector assembly and extends into the connector assembly. The lead-assembly port is configured for receiving a lead assembly. Connector contacts are disposed in the lead-assembly port and are electrically-coupled to an electronic subassembly disposed in the sealed housing. The connector contacts are configured to electrically-couple to terminals of the lead assembly when the lead assembly is received by the lead-assembly port. A stylet port is defined along a second end of the connector assembly and extends into the interior of the connector assembly. The stylet port opens to the lead-assembly port within the interior of the connector assembly to form a continuous passageway with the lead-assembly port.
