资料来源
只使用 FuelTech 自己的资料。针脚名称和说明完全按照 FuelTech 的原文书写。
FuelTech FT450 / FT550 / FT550LITE / FT600 手册
FuelTech 4 缸通用线束手册（为 FT550 编写：针脚相同）
FuelTech 6 缸通用 A 线束手册（为 FT550 编写：针脚相同）

核对方法
- 我们从 FuelTech 这款 ECU 手册中的针脚表入手：针脚、线色和功能。
- 再在第二份 FuelTech 资料中把每个针脚重新读一遍：列出每个 ECU 针脚及其线色的线束手册，FT700 则使用其快速参考。由脚本逐针比对。
- 只有第二份资料给出相同的线色和功能，才会显示该针脚。FuelTech 的通用线以颜色加编号命名（Blue #1 即蓝色输出 1），所以编号也必须一致。
- 标签、说明和线色完全按照 FuelTech 的写法。
ECU Recovery 与 FuelTech 无关联。FuelTech 及其产品名称是 FuelTech 的商标。如果你的线束附带了自己的接线图，请以它为准核对接线。
