An implantable connector used with a neurological device and a lead extension includes a male connector having a plurality of electrical contacts axially arranged along the connector, insulated from each other. The connector also includes a female connector having channels axially disposed therein and a plurality of conductors axially arranged on the female connector. The plurality of conductors are electrically insulated from each other, and at least one indexing element is adjacent the channels. The indexing element allows receipt of the male connector by the channels in a defined orientation relative to the channels, thereby forming at least two electrical connections along two or more axial positions. Often the neurological device is a brain stimulating and recording lead. The male and female connectors are often fastened together with a screw or by twist-locking the two together.
