Use the relay & rectangular plug branch harness form as a starting point and confirm these design points against drawings and the actual equipment.以继电器及矩形插头分支线束的结构形式为起点，结合图纸和实际设备确认以下设计要点。
Relay connection section继电器连接部位
Ends or branches are organized around relay connection points. Routing can distinguish control-side and switched-circuit paths.端头或分支围绕继电器连接位置组织，线束布局可区分控制端与受控回路的走向。
Rectangular interface form矩形接口外形
The rectangular interface form allows end position and service clearance to follow the mating face, latch and cable exit.接口采用矩形轮廓，可围绕插入面、卡扣与线束出口安排端头位置和拆装空间。

PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Can you build both a relay pigtail and a complete fuse-box harness?能制作继电器尾线和完整保险丝盒线束吗？
Yes. The scope can include a pre-wired socket, fused single branch, dual-relay kit or multi-circuit distribution assembly. Drawings, load data, interfaces and installation requirements define the build.可以，范围可包括预接插座、带熔断单路分支、双继电器套件或多回路配电组件，具体结构由图纸、负载资料、接口与安装要求定义。
Can the same assembly work on 12 V and 24 V?同一组件可以同时用于 12 V 和 24 V 吗？
Only when every affected component and operating condition supports both systems. Relay coil voltage, suppression, fuse voltage rating, electronics and load behavior require explicit review.只有相关元件与工况均支持两种系统时才可以，继电器线圈电压、抑制器件、熔断器额定电压、电子部件与负载行为都需明确审核。
Does a larger fuse solve repeated fuse failures?反复烧保险丝可以直接换更大的吗？
Not without reviewing the fault, load, conductor and holder. A larger fuse can leave a smaller branch inadequately protected. Investigate shorts, overload, inrush, poor contact and thermal conditions first.不能未经审核直接加大规格，更大保险丝可能使小线径分支保护不足。应先检查短路、过载、浪涌、接触不良和热条件。
Start with your interface and installation requirements从您的接口与安装需求开始
Share mating interfaces, a circuit table, target lengths or a sample for the relay & rectangular plug branch harness. We can use them to review configuration and sample requirements.提供继电器及矩形插头分支线束的对插接口、回路表、目标长度或参考样品，我们据此梳理选配与样品确认事项。
