Replaced battery, car starts and runs but no electronics work.

[Tetsuichi]

Last night I left my headlights on and killed my battery. I tried jumping it a few times to no avail, and decided I would go out and buy a new battery since this one was several years old.

I replaced the battery, car starts and drives fine, but now none of the electronics work, other than the headlights and wipers.

Radio, dash, horn, brake lights, heat/fans, 4-ways, nothing works. I checked all the fuses and they seem fine, and i can't imagine they would all fry at once. Is there a main fuse or something that I might have blown while jumping the truck?
