External model-reference photograph: Image 4 is a separate unit shown by PcHub, with the supplier's label and connector insets. The reference label reads AVC DFTA0456B2U P039, DC12V 1.70A. Its securing tape and visible harness arrangement differ from the original listing photographs; the full cable is not shown in the main reference photograph. The supplier insets and printed code 2K12291NC do not verify the connector, pinout, batch or actual unit that will be shipped.
