An electrical connection system including a plug-in connector housing for receiving a plurality of electrical signal wires, a plurality of connector contacts retained by the housing, a header body for receiving the connector housing, a plurality of header contacts retained by the body and each positioned so as to engage one of the connector contacts upon reception of the connector housing by the header body, connector keying means selectively disposed at any of a plurality of predetermined positions on the housing, and header keying means selectively disposed at any of a plurality of given positions on the header body and each corresponding to one of the predetermined positions on the connector housing. The individual components are shaped and arranged such that engagement between the connector contacts and the header contacts is prevented by engagement between the connector keying means and header keying means when disposed at any corresponding pair of the predetermined and given positions.
