The later style of Duramax injectors (those outside of the valve cover) can be difficult to indentify.  Sometimes the 10 digit Bosch part number is stamped on the injector body, but in most cases the only numbers that can be located are manufacturing codes.  It is possible however to determine the injector part number by the wire plug connector.  The drawings below show the different styles of connectors and the injector part numbers as well as the applications they are associated with.
