The selector valve

The selector valve is located on the right-hand side of the instrument, behind
the visor. The letters etched on the front of the valve represent the
components to which the associated port is connected. Etched letters with a
light background indicate inputs, while letters with a dark, etched
background indicate outputs. The following table outlines the component to
which each port connects, and whether the port is a fluid input or output.
