STOP THIEF

On my Lexus I found a simple way to disconnect the ignition starter by removing one of the fuses in my dashboard. The car would not start. Does anyone know how I could do this for a 94 E320? Which fuse would I remove or is there ANOTHER way possibly in the interior of the car.
By the way, one failed theft attempt in front of my house when I was vacationing in Aruba. Luckily I removed the fuse that week but they made a mess with the ignition starter and the lower dashboard panel.

Thanks,

Ron
