Wire color codes
Wire traces on wiring diagrams are labeled with alpha codes. Refer to Table B-2.
For Solid Color Wires: See Figure B-1. The alpha code identifies wire color.

Figure B-1. Connector/wiring diagram symbols: 1. Connector number; 2. Terminal code (A=pin, B=socket); 3. Solid wire color; 4. Striped wire color; 5. Socket symbol; 6. Pin symbol; 7. Diode; 8. Wirebreak; 9. No connection; 10. Circuit to/from; 11. Splice; 12. Ground; 13. Twisted pair
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 B-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 ofa 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.
