went to autozone to buy a new battery and somehow the guy who helped me sold me a battery for a 7mge and not realizing the terminals are different, i connected the positive to the negative and the negative to the positive terminals and holy spark.. took battery back to autozone and got the right one.. came back and connected battery and no light in dash.. only head lights and gauges works.. checked all the fuses inside car and inside engine and none are blown.. did i blow something else? relays?

How about that "alt" fuse under the hood? It's just a thick wire

Depends on year, early ones have the wire, late have the actual fuse. It's bolted in from the bottom so it requires disassembly of the fuse box to get out. Back to the question, yes, that's usually what blows, and if that blows you get zero power to the car.

Yes, batteries are the same from NA to Turbo, but our poles are opposite of a "normal" battery. I extended my cables so I could use a normal battery simply because of availability.

Fortunately for us, that's what usually blows. I know a guy who had a Mitsubishi (I think, could be wrong), and the PCM was what would blow for him. And it wasn't cheap.

Sounds like a Voltage Spike through your system. If you have a Fusible link or Fuse, check either. Not sure which one applies to you. I'd say get in there and check to resistance with a Multimeter if you have the link.
