Connector
The connector pin shape determines whether the con-
nector is male or female.
The connector housing configuration does not deter-
mine whether a connector is male or female.

The symbol illustrated in the figure is used as connector,
in the circuit of this section.

Connector is identified with a number.

The applicable terminal number is shown for each con-
nector.

Connector terminal numbers are clearly shown.
Male side connector terminal numbers are in sequence
from upper right to lower left.
Female side connector terminal numbers are in se-
quence from upper left to lower right.

Notice:
For those connectors on which specific terminal num-
bers or symbols are shown (such as ECM), the terminal
numbers or symbols are used in the circuit diagram, ir-
respective of the above rule.

The connectors used for relays have their own terminal
number assignment, irrespective of the above rule.
