Anyone know where the ground locations are on a 2500?

Having some electrical issues and I suspect I have a loose or faulty ground. Anyone know if they are different than the 1500 (I believe they are). The guys on that side were not sure.

Let me know which of these you are interested in and I'll post the info.  Don't tell me all of them, but do tell me the year.
