Power problems

So, I have a 1994 Toyota pickup that gives some
strange symptoms to the electrical system. It had
previously behaved as though the battery was shot,
so today I dropped a new battery in the truck.
However, it will not start and is worse than before.
As of now I get power to a select few devices(horn
works, headlights work, dome light works, door
buzzer works), but none of the others(radio won't
work, brake lights do not work, starter won't turn at
all). I had read before that the fusable link might
have gone out, but that would interrupt power flow
to the whole truck, not just half of it. Am I missing
something simple here?
