What I did next was take apart the underhood fuse box. I found that removing the two large fuses made the draw go away. The reason it didn't before is because I removed them individually. Both removed together and problem is gone. Its the two fuses labled "Lighting", and "Battery". I looked up in the chiltons I have and Lighting is broken down to "headlamp panel dimmer switch, fog & courtousy fuses". Battery simply states "fuseblock busbar" and that is it. Are these two circuits tied to one another? I wish chiltons would give a little more detail.
I also removed the interior fuses in the drivers door jam one by one with no change.
Any one have any other ideas?
Please stick with me on this one, I just don't know what else to do next and really need to get this one figured out soon. 5A is WAY to excessive of a drain, it will kill the battery if I keep it plugged in and just keep charging it up.
Thanks for the help thus far. I will have more time to do some more testing tomorrow morning before work again providing the weather is good.

On the alt unplug make sure you unplug the plug in and the batter wire to.
Strange on having to pull both fuses lighting and battery to stop the amp drain.
Also remember when testing for amp drain give the computers time to power down.
Sometimes 20 -30 minutes for power down.
Run that test on the lighting and battery fuse again.
The circuit that is drawing amp should show up on one fuse at a time.
I looked at Mitchell power feed and it does not show them very good.
The lighting fuse feeds the lighting stuff into other fuse boxes and switches.
If all else fails and you do not have a factory repair manual on the wiring and fuse power feed diagrams you might try a Online All Data DIY repair info sub.
