I will be purchasing a used DCX Unmarried tomorrow. I have already registered on the site. I will validate that it is unmarried prior to purchase. What will I need to do with it once I plug it into the computer USB? I have a 2012 Dodge Ram Sport 1500. Thanks

I will be purchasing a used Unmarried DCX 1000 tomorrow for my 2012 Dodge Ram 5.7. I will validate it that it is unmarried; once I get it to my computer how do I register the device and update for the truck. I registered on the site today but want to make sure that I know what to do once I plug it ...
