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。

Vehicle Tracking 14-Pin T-Branch Harness车载定位14针T型连接线束
Vehicle Tracking 14-Pin T-Branch Harness can be configured around equipment interfaces and routing. A vehicle tracking installation combines separate RF, power and data paths. Their cable, connector and verification requirements are not interchangeable.车载定位14针T型连接线束可围绕设备接口与安装路径进行配置。车辆定位安装同时涉及射频、供电与数据路径，这几种回路的线缆、接头和验证要求不能混用。

PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Does one GPS harness fit every 12 V vehicle?一套 GPS 线束适配所有 12 V 车辆吗？
No. Supply voltage alone does not define connector pinout, ignition behavior, vehicle data access or installation geometry. Confirm the exact platform and tracker.不适配。供电电压不能单独确定针脚、点火逻辑、车辆数据访问或安装形状，需要确认具体车型与定位器。
Does a longer antenna cable improve reception?天线线缆越长，接收就越好吗？
Only if relocation improves the antenna environment enough to justify the added loss. Length itself does not amplify the signal; verify the receiver and antenna link budget.只有改善天线位置带来的收益足以抵消新增损耗时才可能有帮助。长度本身不会放大信号，需要审核接收器与天线的链路预算。
Can the harness convert CAN data into GPS reports?线束能把 CAN 数据自动转换成 GPS 报告吗？
A passive harness cannot. Data interpretation and reporting require compatible gateway electronics, software and authorized access.无源线束不能。数据解释与上报需要兼容的网关电子设备、软件和授权访问。
