KX155/165 Nav units have dual GS outputs. Use
“Numbered” or Lettered pins, not both. Use unused
pins independent from those driving a backup NAV
indicator if possible. Otherwise parallel as close to
NAV receiver as possible (see Figure 9-24 & 9-25)

If paralleling GS signals with backup NAV indicator
then splice wires as close to NAV receiver as
possible. Do not parallel at back of NAV indicator
(see Figures 9-24 & 9-25)
