Where is the fuse box located?

I did some digging in the T-Bird Forums (http://www.tbirdforum.com/forums/forumdisplay.php?f=14), and it sounds like your '61 T-bird doesn't have a fusebox. Each power line to an electrical component contains its own fuse. It also sounds like messing with the wiring in a '61 can get pretty ugly if you're not very careful to take note of how stuff looks before you dig into it. Hope that helps, benjammin308!
