CAT 357-2083 is an engine control module listing. Before requesting a replacement, read the full identification on the removed ECM. Keep any secondary labels in the photograph rather than cropping the image down to the large part number.
An engine family name alone leaves unanswered questions about the unit installed. Include the engine identification and show both the connector face and mounting side. If the controller came from a machine bought used, distinguish what is visible on the unit from information supplied by the previous owner.
For a 357-2083 enquiry, send those photographs with the quantity needed. Ask which details have been confirmed and which still require checking before accepting a quotation. The CAT parts range contains other listings, but a neighbouring part number is not evidence of interchangeability.
