Cummins 4993120 ECM ECU Module
Cummins 4993120 is an ECM ECU module for buyers who already have an old controller to identify. The label number starts the check, while the connector and the installation details help avoid a wrong match.

There is no fixed equipment claim on this page. The application should be taken from the engine or equipment where the old 4993120 unit was installed.
What The Buyer Should Send
- label photo where `4993120` can be read;
- connector photo with the pin side and locks visible;
- engine model or equipment name;
- full housing view, including mounting points;
- quantity and destination country.
If the machine is down, ask the technician for the label first. A straight connector photo is useful too, especially when the number on the label is partly worn.
A Similar ECM Is Not Enough
Two Cummins modules can share a similar housing while using different connectors or control details. Check the original 4993120 unit and its installation before discussing the final part.
Quick buying check
Buy this 4993120 unit only after the old label number, connector shape, housing view, and equipment information match your machine photos.
