Terminals and
connectors-Different terminal symbols are
used to indicate male terminals,
which are inserted into another
terminal, and female terminals,
which receive other terminal. A
connector containing male
terminals is called a male
connector, and a connector
containing female connectors is
called a female connector. The
connector symbol for a male
connector has a two-line outline,
whereas the symbol for a female
connector has a single-line outline,
in order to distinguish them in the
diagrams.
Connector
symbols1The symbol shows the connector
used in the actual vehicle, as
viewed from the direction of the
illustration. At the connection with
the device, the connector symbol
on the device side, and the
intermediate connector are shown
by male connector symbols.
Spare connectors and inspection
connectors are not connected to
the device, and therefore, these
are represented by a harness side
connector symbol. Note, however,
that the above does not apply to
diagnosis connectors.
