At the worst, you fried your PCM (computer). At the best, you fried a fuse in one of the three fuse boxes - there is also a good possibility that you completely discharged your battery with that escapade and you may just need a new battery.

Step 1: Take a volt meter to your battery if you have less than 10 volts, its not enough to energize the computer and system.

Step 2: If you DO have proper voltage, check all 3 fuse boxes for blown fuses and relays (relays can be tested using a multi-meter and diode test - find a relay test how-to)

Step 3: If your fuses and relays are good....it's time to take it to a mechanic because the troubleshooting after this is more than a lot of people can handle.

Good luck!
