head unit, no power, no interior lights

I just uninstalled a panasonic head unit and replaced it with a Kenwood Excelon KVT-819DVD in my 2002 Dodge Dakota. I had it working great and all hooked up but not in the dash yet. Then after installing it I got no power at all. I tryed hooking up the old (panasonic) deck with no luck. Thinking it might be a fuse i checked all of them and nothing. I tested the battery (constant) wire (pink) in the factory harness and not juice to it. At this time i realized that i had no interior lights and my gauges were kinda acting wierd and not coming down when the truck was shut off. I am confused as hell at this point. I really hope someone can help me out with this one. -Thanks-
