Thanks, that did help. I just found the pepakura files for the armor I'm looking to build Halo 4 MkVII armor. And if I build it the way I want to, will I have to install cooling fans? I've thought about it before, and now that I'm moving forward with the project, I think I may have to devise a clever way to keep the armor cool.(I live in Nevada, where it gets crazy hot in the summer) Also, If I do put in cooling fans, would I be able to tie them into a power source along with lights in the helmet? I've thought about this as well, and I believe it would be hard to do, and I may have to power the two seperately, with the lights in the helmet being run by a separate power source within the helmet.
I would recommend having cooling fans, regardless of where you're at. They help defog the visor as well. You would be able to tie them into a single power source, as I've seen people use male/female connectors (like 9v power adapter ends) to attach the current to other pieces of their suit. That should be able to work, if you run the cable up your neck under your suit and into the helmet.
Also, if you work with metal, be careful about shorts. I'd hate to see a piece of armor ruined by a exploded battery or other phenomena.
