My opinion, now that you have the car, start a build thread before you post up any other questions or progress. Start it with pics of the car and your plan. If you do start a build thread, please post a link to it in this thread so I don't miss it. I'd like to watch this one and would probably miss it otherwise.
For the wires, trace where they're coming from and post that info. Too hard to decipher (for me anyway) from the pics.
