Electric Problems

Hi I'm a lil new to this but I have a Question. I was wondering if anyone out there could shed some light on a bonehead blunder I made. I accidently hooked my battery back up with the positive on negative and vice versa. I think I might have blown some fuses by reversing the polarities because she won't start for me now although, I did get it to start when I went to see if my battery was the problem at autozone. It took a couple cranks but it started. I have a brand new alternator and Ignition switch. My solenloid/relay is relatively new and my starter is fine. I really wanna know where my fusebox on this model and year. Being that money is kinda tight right now I can't go out an grab an owners manual. Sorry for writing a novel but once again I'm new. I hope someone can answer my question/prayers.

Thank you

Year, make and model? you might have 2. One under the hood and one under the dash. You might have damaged the computer.
