987 wont start after pulling the security box under seat

[2013grandsport]

so I checked connections and have no bent pins all is well under the seat. Car still will not turn the engine over. For some reason when you turn the key on it kicks the cooling fans in the bumper all the way on high speed, Also says PSM failure, abs failure, rear spoiler failure on the instrument cluster. This is so stupid! All I did was unplug the box under the driver seat. I did not get it wet and I did not change to a different box from another car. Everything in the car worked flawlessly before I removed it. This was august 2015, and I have been unable to start the car since. I feel like the dealer is going to try and rob me and convince me I need a new box.
