Wire Color Codes
Wire traces on wiring diagrams are labeled with alpha codes. Refer to Table 1.
For Solid Color Wires: See Figure 1. The alpha code identifies wire color.
For Striped Wires: The code is written with a slash (/) between the solid color code and the stripe code. For example,
a trace labeled GN/Y is a green wire with a yellow stripe.
Wiring Diagram Symbols
See Figure 1. On wiring diagrams and in service/repair instructions, connectors are identified by a number in brackets
[ ]. The letter inside the brackets identifies whether the housing is a socket or pin housing.
A=Pin: The letter A and the pin symbol after a connector number identifies the pin side of the terminal connectors.
B=Socket: The letter B and the socket symbol after a connector number identifies the socket side of the terminal
connectors. Other symbols found on the wiring diagrams include the following:
Diode: The diode allows current flow in one direction only in a circuit.
Wire break: The wire breaks are used to show option variances or page breaks.
No Connection: Two wires crossing over each other in a wiring diagram that are shown with no splice indicating they
are not connected together.
Circuit to/from: This symbol indicates a more complete circuit diagram on another page. The symbol is also
identifying the direction of current flow.
Splice: Splices are where two or more wires are connected together along a wiring diagram. The indication of a splice
only indicates that wires are spliced to that circuit. It is not the true location of the splice in the wiring harness.
Ground: Grounds can be classified as either clean or dirty grounds. Clean grounds are identified by a (BK/GN) wire
and are normally used for sensors or modules.
NOTE
Clean grounds usually do not have electric motors, coils or anything that may cause electrical interference on the
ground circuit.
Dirty grounds are identified by a (BK) wire and are used for components that are not as sensitive to electrical
interference.
Twisted pair: This symbol indicates the two wires are twisted together in the harness. This minimizes the circuit's
electromagnetic interference from external sources. If repairs are necessary to these wires they should remain as
twisted wires.

Function/Location
All vehicle connectors are identified by their function and location. Refer to Table 1.
Place and Color
The place (number of wire cavities of a connector housing) and color of the connector can also aid identification.
Connector Number
On wiring diagrams and in service instructions, connectors are identified by a number in brackets.
Repair Instructions
The repair instructions in Appendix B of the electrical diagnostic manual (EDM) are by connector type. Refer to Table
