摘要总结AI 辅助解读
该条款规定美国商用车辆电气布线须符合 SAE J1292（1981年10月版）标准，但跳线电缆插头和插座无需符合 SAE J560。明确引用 SAE J1292 不要求拖车具备电路保护功能。此为技术性合规细节，主要涉及车辆硬件维护标准，对跨境物流业务流程无直接重大变更影响。

The reference to SAE J1292 shall not be construed to require circuit protection on trailers. (See § 393.7(b) for information on the incorporation by reference and availability of this document.)
