The symbol indicates the 
connector is viewed as shown. 
At a device connection, the 
connector symbol on the device 
side is shown. For an 
intermediate connector, the 
male connector symbol is 
shown. For spare connectors 
and check connectors, no 
device is connected, and so the 
harness-side connector symbol 
is shown for these connectors.
However, a diagnosis connector 
is exceptional.
