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 这款 ECU 的手册（线束接线表）
FuelTech FT450 / FT550 / FT600 手册第 9 章：逐线列出的旧款线束
同一本手册中的 FuelTech 插头图，人工读取
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。
FuelTech 资料之间的不一致之处
MAIN 8：FuelTech 的 FT550 手册（第 9.1 章，逐线列出旧款 FT350 线束）漏掉了这根线。FT350 手册在针脚表和插头图上都列出了它（'Auxiliary Output #4 (Yellow)'）。
MAIN 10：FuelTech 的 FT550 手册（第 9.1 章，逐线列出旧款 FT350 线束）漏掉了这根线。FT350 手册在针脚表和插头图上都列出了它（'Ignition Output - E'）。
MAIN 13：FuelTech 的 FT550 手册（第 9.1 章，逐线列出旧款 FT350 线束）漏掉了这根线。FT350 手册在针脚表和插头图上都列出了它（'MAP Signal Output - Yellow/Red'）。
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。
