I bought a 96 swapped civic not too long ago, and now the key is stuck in the ignition. It will still go into accessory and start the car. Only way the key will come out is if I disconnect the battery.

I did some searching and found out the car used to be auto. I'm guessing it doesn't think it's in Park or netural anymore.

 

You will need to find the automatic shifter wiring switch plug in the center console and verify that the "P" wiring pair is connected... if the shifter switch is missing, you will have to connect the wire pair at the plug. Your REVERSE wiring is also found here if you want to verify that your back-up lights work properly.
