		• The power supply line on the circuitry are found in
	A	the upper space of the circuit diagram.
		• Power supply lines are #30, 15, 15a,15b, 58
	B	• F31 : Fuse number, 15A : Electric capacity.
	C	• This section shows the parts name and the pin
		number.
		• This section represents the connector where different
	D	wirings are connected to each other.
		C201 indicates the kind of connector, while the #3
		means that it is the third terminal of the connector.
	E	• This section shows the color of the applicable wire.
		- BR - : Red stripes on black ground.

• This section indicates the location of ground Connection.

F• The bottom line is a battery(-) line or ground(#31). ( G : ground )

•There are a number of cross lines.

A crossing having a dot as in “B A ” means that the

Glines A and B are connected to each other. On the other hand, a crossing having no dot indicates that the lines A and B are separate lines.

H

• This section indicates the body ground Connection. so, there is no wire ground like Gxxx.

1-2. POWER SUPPLY NUMBER

NUMBER

CONTENTS

30 • The battery(+) line.

15• Electric power is supplied when the starter switch is turned to the "ON" position before the engine starts.

15A • Electric power is supplied when the starter switch is turned to the "ACC" position.

15B • Electric power is supplied from the starter switch "ON" relay #87.

58 • #58 is switched ON when the head lamp switch is ON.
