Car won't start

I have a 1993 Nissan NX2000.

My car won't start. No dash lights come on when I turn the key, the radio doesn't come on, etc. But I can turn on the headlights just fine. The battery has power. I replaced the ignition switch (It needed to be replaced anyways) but still have the same problem. I checked all of the fuses I could find and none of them were blown, but I just KNOW this is a blown fuse somewhere. What should I be looking for?
