I've got the 2007 Quad cab, 4X4, Hemi with MDS.... Has anyone wired up a light or had a dash light wired as to come on when the MDS system turns on...??? I Thought It would be super to know when It was working... Doug

The edge programer I'm beta testing has a read out on the screen that indicates V4 or V8. Put on an aftermarket exhaust and you will be able to hear it when it goes back and forth.

You could easily mount one of those aftermarket tachometers that have the clamp the grabs one of the sparkplug wires and reads the electrical pulse. Just be sure to put it on one of the sparkplugs that shut off when the MDS is on.

I read a post a while back of someone that did that, picked the wire from the solenoid that controls the valve shut down.

There is a lead in the computer that can be tapped. It can light a LED to show when the # ___ cylinder has been deactivated. There are several posts on Chrysler forums showing the procedure. Sorry for lack of info. I'll try to find the post, but it's been a while since I read it. Guess it may not apply to the trucks anyway.
