CONSTRUCTION结构解析
Connection structure and design details连接结构与设计要点
Use the map manifold pressure sensor 3-wire plug pigtail form as a starting point and confirm these design points against drawings and the actual equipment.以MAP歧管压力传感器三线插头尾线的结构形式为起点，结合图纸和实际设备确认以下设计要点。
Pigtail connection form尾线连接形式
A lead section extends behind the connector, allowing length, further termination and support to follow the equipment connection.插接端后保留引线段，便于按设备接线位置确定长度、后续端接与支撑。
Trunk and branch layout主干与分支
Locate trunk and branch datums from equipment fixing points. Allow room for mating, bends and servicing so branches do not transfer installation loads to contacts.以设备固定点确定主干和各支路的尺寸基准，预留插拔、弯曲和维护空间，避免支路把拉力传递到端子。
Conductor and insulation selection导体与绝缘选配
Select conductors and insulation from circuit loads, diameter limits, bending and exposure. A material name does not replace ratings or validation results.从电路负载、外径限制、弯曲方式与环境条件选择导体和绝缘体系；材料名称不应直接代替额定参数或验证结果。
Interface and function review接口与功能确认
Oil-resistant jackets are not automatically suitable for fuel immersion耐油护套不自动适合浸泡燃油

PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Is a fuel-system harness the same as a fuel line?燃油系统线束等同于燃油管吗？
No. The harness carries electrical power and signals to pumps, injectors, valves and sensors. Hoses, rails and pipes carry fuel and require separate fluid-system engineering and verification.不等同。线束向泵、喷油器、阀和传感器输送电源与信号；软管、油轨和管路输送燃油，需另行开展流体系统设计与验证。
Can a connector that fits an injector be used directly?喷油器插头能插上就可以直接用吗？
No. Confirm the injector and controller part numbers, cavity view, driver strategy, circuit assignment, terminal system and installed environment. A shared shell shape does not prove electrical compatibility.不能。还需确认喷油器与控制器料号、孔位视图、驱动策略、回路分配、端子体系和安装环境。外壳形状相同不证明电气兼容。
Does a sealed connector make the whole harness fuel-resistant?密封接头能让整根线束耐燃油吗？
No. Fuel exposure must be defined by liquid, vapor or mist, duration and temperature. Wire insulation, seals, protection and the mated connector all need suitable material evidence and an agreed test if a resistance claim is required.不能。应明确是液体、蒸气还是油雾，以及接触时长和温度。若需耐受声明，线材绝缘、密封、防护及对插连接器均需对应材料证据和约定试验。
