electrical questions, replaced fuses, then... Options

[double-a]

i replaced all the fuses on the fuse block today, many looked quite sorry indeed. now, after doing so, the headlights do not rotate up or turn on, no fog lights, and no wipers either. on the front of the fuse panel, all fuses are good, and i think they're all in their correct places. on the backside, everything looks good. there is, however, a wire up under the dash, near the fuse panel but not connected to it, that is a single spade with four brown wires. does this go anywhere on the block? and if not, what would happen if it had touched something on the back of the fuse panel?

thanks for any help. i did consult the color wiring diagrams, they are little help to me unfortunately. i'm good mechanically, but not much of an electrician. i would very much like for my headlights to work!
