Is beside the fender on the lid it’s calls it joint connector 2

Hi drove my 1999 3500 24v truck to work the other day and parked came back to it in the evening and whent to start it, first thing i noticed was no wts light.It turned over but fail to start and no fuel pump and no bus showing in odometer. Popped the hood and could smell burnt wires. The joint connection 2 in the pdc burned up the local dodge dealer told me that usually the pdc gives out 90% of the time the pdc shorts out its self and causes this but I'm not sure about that. I got a good used one from a local parts truck my plan is to clean all the grounds and check for shorts then I will hook the batteries back up and pull what codes i can. Just wondering what else i should do to prevent it from happening again or does anyone have an idea what might have caused it in the first place.would be thankful for any feed back. Dale
