6.0 no start.

Brother has an '03 6.0 it's not starting right now trying to find key on power to hook my black Maxx up to pull codes any help?

What does it have for ICP? codes? FICM voltage? fuel pressure? sync?

I can't read any of that until I get key on power for my black Maxx. Anybody know the wires under the dash that can help?
