Get your new volt meter out and see if you have power on the pin on the right side of the notch for the plug on your 7round trailer plug, that should be +.
If no power there look in your owners manual. (Sorry don't know the details on dodges. I've mainly worked at gm dealers and now an auto group that also has a ford store that we do a lot of work for)
