a) Special feature : The various circuits are presented in a functional way, therefore, where a unit is connected
to several circuits, its various sections are shown in CC exploded )) form on different vertical grid lines. i
b) Method of identification : Identification marks are divided into three sections
‘; - figures which identify components ( and not leads )

: Identification marks for components and wiring harnesses are arbitrary they have been chosen
for the sole purpose of facilitating the use of the diagrams.
The colour of the sl~~e~-cs arld the leads are the only.identijication marks actually used ow the leads making
up the electric system oj the r;ehic!e. 2. WIRING DIAGRAM
This is a schematic diagram of the components as they are fitted on the vehicle.
It indicates the layout of the leads, and the approximate location of the components.
The method of identification is the same as for the circuit diagram.
