The spare external pin in the power connector is connected to an option by linking the
appropriate option pin to the EXTERNAL pin on options connector S14 (refer to Section
5.9, “Options Interface Specifications”).
The recommended linking method is to crimp a short length of 7/0.2mm PVC wire
between the appropriate connections on a 16-way Micromatch plug (IPN 240-00026-24),
which can then be plugged onto the options connector.
