线束导线识别
Caterpillar 使用 11 种固定颜色来识别所有导线。 电路号以 25 mm (1 in) 间隔压印在导线上。 表 1列出了这些导线颜色和颜色代码。

| 线束导线的颜色代码 | |||
| 颜色代码 | 彩色 | 颜色代码 | 彩色 |
| BK | 黑色 | BU | 蓝色 |
| BR | 棕色 | PU | 紫色 |
| RD | 红 | GY | 灰色 |
| OR | 橙色 | WH | 白色 |
| YL | 黄 | PK | 粉红色 |
| GN | 绿色 | ||
比如，示意图上的导线识别标记F730-OR 表示这是一根橙色导线，其电路号为F730。 F730-OR代表机油压力传感器的电源线。
注: 更换线束时，务必使用相同直径规格和色码的导线。
注: 在下图中，"Pxxx"表示一个插头，而"Jxxx"表示插座。
