Engine Wiring Information
1.1. Harness Wire Identification
2.1. Schematic Diagrams
AVSpare identifies all wires with eleven solid colors. The circuit number is stamped on the wire at a
Show/hide table
Color Codes for the Harness Wire | |||
Color Code | Color | Color Code | Color |
BK | Black | BU | Blue |
BR | Brown | PU | Purple |
RD | Red | GY | Gray |
OR | Orange | WH | White |
YL | Yellow | PK | Pink |
GN | Green |
For example, a wire identification of F730-OR(Orange) on the schematic would signify an orange wire with the circuit number F730. F730-OR(Orange) identifies the power supply for the oil pressure sensor.
Note: Always replace a harness wire with the same gauge of wire and with the same color code.
Note: In the following diagrams, "Pxxx" signifies a plug and "Jxxx" signifies a jack.
