HOW TO READ CONFIGURATION DIAGRAMS
NOWCAI
The wiring diagrams are prepared rn such a way that the arrangement of connectors for each vehicle, and the
routing of each harness, can be easily understood for each individual wiring section.
Indicates the connector number.
The connector number used is the same number as that used for circuit diagrams;
these numbers facllttate the location of the connector positions.
The alphabet letter used as the prefix represents the wiring section in which that
connector is used; subsequent numerals make up the number that Indicates
particular characteristics of that individual connector. As a general rule, numbers are
assigned clockwise around the wiring diagram.
Note that, if there IS a concentration of connectors with the same form (same
number of pins). the connnectors’ colors are noted in order to facilitate identification.
