Quadzilla stopped working after unhooking battery's
 

I have a 1998.5 dodge 3500. I had to unhook the battery's for some tranny work and they were unhooked for about 2 weeks. When all got back together my quadzilla turns on and displays perfect. But has no communication with the truck what so ever! I've tried it all from unhooking battery's for an hour to trying to load a new tune to the box (but of course my computer can't find the quadzilla once it try's to look for it!)
It is the quadzilla xzt+ power module. It was on the truck when I bought it and I miss the power like crazy! I'd loveeee for someone to be able to help me out with this!
I'm so lost and confused.
It only has two wires plugged up to engine. Plus the power and ground. I'm really new at the whole diesel thing. Please help:argh:
