2024 ram 2500 6.4 Do I have an Eco light on my dash to tell me if the MDS is on or off?

If your engine will go into 4-cylinder mode, then you should have an ECO light.
The answer just might be in your owner's manual. Try to read it.

You may have to enable the ECO light through the uconnect screen. I did on mine. But since yours is a 2500, it may be different. Try asking over at Homepage - HD Rams

In your radio, vehicle > settings > display > fuel saver display > on.
This setting is what makes the eco mode light show up in the cluster if MDS is on.
