It's near the firewall but its between my windshield washer reservoir and my fuse box tucked in the corner by the driver door

 

Mine is a 87 so it is considerably different under the hood.....
Is it possible that it is the feed for the windshield washers?

 

No, that was my first thought. I tried rewiring those 3 wires with a new one and ran it to a ground, negative and positive on the battery and even to the starter and none of those seemed to do anything to help

 

I have been thinking about this and the tube that is open, it may go to the gas tank as part of the vent system. After re-reading you said the one line went to the starter fuse? I believe that would have to be a positive wire. Are you sure you stripped back far enough and have a good connection? Is the fuse good?
In addition, You may have other problems, ie bad switch etc. I really believe you need to come up with a schematic and start tracing out the voltage flow and see where you are loosing it.
I think, in the FAQ section of this forum, there is a link to a PDF copy of the 95 dakota..... It may be close enough to figure out what is going on without having to purchase a manual
