WIRING - INTRODUCTION TO CIRCUITS 71-3

* The system shown here is only an example system, and differs from actual system
circuit diagrams.

Note

NO. Name Description
System names are designed to distinguish different systems and

functions, which can be easily found.

Normally, the wire uses a signal color or dual color. So to distinguish
wires of different functions and for ease of search and repair.
2 Wire color
E.g.: R (Red)
Blue - Black (Blue and Black)

Define the wire number according to the harness belonging to the
electrical component connector, easy to find. E.g., the hazard switch
4 Component no. connector is a 6-pin connector that belongs to the body harness.
The body harness is defined as B harness, therefore the hazard
switch no. should be B001.

Determine the sequence of electrical component connector pins,
easy to find and repair. The conventional sequence is: the socket
sequence for electrical components (unless otherwise specified).
Electrical component sockets.

This sequence fits for the connector numbering too.

It is the connecting point between the electrical component return
