What does this wire do? Electric truck repair team is looking for some help

I know that there's an Open Source Car, but I haven't heard about an Open Source truck repair project? Some folks who blog over at Blogspot have found themselves in possession of a GMC S15 truck that has been converted to run on batteries. The trouble is that there are some loose wires here and some rust spots there, and the guys with the truck don't seem to know enough about EVs to figure out what needs to be done to make things right. I figured AutoblogGreen readers would know a thing or two about a thing or two, so here are the links to the photos and a little bit of the description of what the truck is all about.

Anyway, if you're at all knowledgeable with repairing trucks and/or electric components, these guys could really use the help. Right now, the only comment anyone has left on the blog reads, "Good luck."
