Notes

C1791 is a cable product for photovoltaic system interconnection, not an electronic component. It has two conductors (one per wire) with no discrete pins or pinout diagram. The attached cross-section diagram shows the internal structure (conductor, insulation, identification thread, and sheath) but does not represent a pinout. No pin numbering or electronic pinout table is applicable to this product.
