Help!!!!!! EMS problem or not?

[Precision]

So I was putting the final touches on my car to go to a test and tune tomarrow. While trying to figure out why my wideband wasn't reading in my EMS I some how and I don't know how quickly crosed the main power and main ground wires going into my ECU.

Now that I feel like the bigest dumb ass in the world becuase it seems that only this crap happens to me the day before I want to go to the track.

My questoin is dose any one know what may have "poped" I.E. relay, fuse, ect. The EMS is reading no crank pulse and the map is no longer reading any more. Please help!!!!

Ok, after I cooled off I went back out and checked fuses, 20 amp motor fuse was blown. Replaced it and now runs like a cham again.
