that's called the sail and is a good location in a lot of cars.

I have some 1/0 welding cable but it's not overly long, if you tell me how long you need I'll measure it, it ran from my alt to my trunk in an intrepid so it might work, I also have a fused power distribution block with led display brand new if you're interested, it's a tsunami, I can't find the exact one on the net but I will take pics if you're interested.

prices will be more than fair I assure you,.
