if you just watch your tach while driving for a while you will be able to tell when the mds pops on. I could tell a month after i got my 07 and then added exhaust and could hear it. when cruising you will see it jump up 2 or 300 rpm all the sudden and when you hit resistance see it drop back down. Otherwise my edge evolution has a monitor that tells you when it is in mds mode also. Dont know about the do it yourself job though???

After looking at the wiring diagram, it seems to me that installing one wire from a 12V led to a MDS solenoid wire and the other wire to a ground would be all you have to do.
