1 System Designation

2 Harness Connector NO.

The numbering rule of harness connector in this circuit catalogue is based on harness,

For example, the serial number of harness connector of left front headlamp among

engine harness is E23, E means harness code, 23 means the serial number of

connector.

Each code in the following chart represents the corresponding harness：

If the wire is bicolor, the first letter represents the background color, the second letter

represents the streak color, “/” separates the two letters in the middle

For example: the wire marked by G/B means green background

and black streak.

7 It displays the wire diameter.

8 It displays the terminal numbering of connector, attention,the terminal numbering

sequence of mutually connected harness connector mirror each other, see as

following diagram：

Caution：

1 Some butt-joint harness connector numbering among harness is differnet.

2 For harness connector numbering, please refer to layout diagram of harness.
3 Component designation

4 It displays the relevant system information of circuit connection.

5 Connection between plugs, the serial number of butt-joint connector is marked on

the side.

6 It displays the wire color and diameter, the color code is as following:

9 the serial number of grounding point, the identification of serial number starts

with G. For the position of grounding point, please refer to layout diagram of

grounding point.

10 Wire node.

11 The fuse numbering is made up of fuse code and serial number, the fuse code

which locates in engine compartment is EF, interior fuse code is IF. For fuse
numbering, please refer to fuse list.

12

The relay numbering is marked by single English letter. Please refer to relay list.

13 If relevant circuit design is different due to vehicle model 、 engine type or

configuration, the different part will be marked byhidden line and instructed on the

circuit side.

If 8-shaped identification is marked between circuit wires, it 如 represents that the circuit

is twisted pair, which is mainly used for signal circuit of sensors or data communication

circuit.

14

If the content of a system is pretty much and the circuit needs to be expressed

by many pages,

the starting point of circuit is represented by

the

destination point of circuit is represented by

if one circuit in a

diagram shifts to next page, it should be represented by letter B or C
accordingly, and so forth.
