Ignition switch problems

I have a 1997 honda civic EX. 4 cylinder automatic with about 185k miles. someone recently tried to steal it by removing the back side of the ignition wire harness. I replaced the whole wire harness that connects to the ignition, that was the only part that was tampered with. I cant get any type of spark at all. The ignition dont have a security switch so that is not the problem. I spoke with the honda dealer,He said the computer might have to relearn itself. Is it anytype of reset button i can push myself or could it be something else?
Thanks in advance for any advice you have for me.

Best Regards,
O. Thomas
