1. HOW TO READ ELECTRIC WIRING DIAGRAM

1) CONTENTS OF ELECTRICAL WIRING DIAGRAM (CIRCUIT)

POSITION	EXPLANATION
A	- Upper horizontal lines : Power supply lines - Power supply lines : 30, 15, 15A, 15C, 58
B	- Ef20 or F2 : Fuse Number Ef20 : Fuse No #20 in engine room fuse box F2 : Fuse No #2 in passenger room fuse box
C	- Connector (C101~C902) Connector No C203 terminal No1 Refer to Major Connector Position (Section 2)
D	- S201 : Splice pack (S101~S303) Refer to Major Splice Pack Position (Section2)
E	- Internal circuit of component (Relay) (Component Name and Terminal Number)
F	- Internal circuit of component (switch) (Component Name, Terminal Number and Connecting Wiring Circuit)
G	- Wiring Harness Color Refer to Wiring Harness Color Abbreviation
H	- Lower horizontal line : Ground line Ground position(G101~G401) B : Body Ground Refer to Major Ground Position (Section2)

2. CIRCUIT IDENTIFICATION SYMBOL

IDENTIFICATION SYMBOL	MEANING
C	Connector
D	Diode
Ef	Fuse in engine room fuse box
F	Fuse in passenger room fuse box
G	Ground
S	Splice pack(Junction connector)

3. FUNCTION OF POWER SUPPLY LINE (NUMBER)

Power supply No	Power supply condition
15	Battery Voltage(B+) supply in Ignition Switch "ON" and "ST" (IGN 1)
15A	Battery Voltage(B+) supply in Ignition Switch "ON" (IGN 2)
15C	Battery Voltage(B+) supply in Ignition Switch "ON" and "ACC"
30	Battery Voltage(B+) supply directly regardless of Ignition Switch
31	Ground connected to battery(–)
58	Battery Voltage(B+) supply in Head Lamp Switch 1st and 2nd step (Illumination circuit)

4. WIRING HARNESS COLOR IDENTIFICATION

5. HOW TO CHECK TERMINAL NUMBER OF CONNECTOR

- Terminal number is given based on Female Terminal Connector

ex) Terminal Number 4 of C901 connection
