Technical Stilo wont start - Fuse Blown

Hi All, I have a non-starting Fiat Stilo 1.4 that I hope you can help diagnose.
This initial issue problem was that the engine would turn but not start. The padlock sign came on the dash with " check protection system" or words to that effect shown on the display.
I gave it to a guy that knows a bit about cars and he found that a fuse had gone under the bonnet - F18. He replaced F18 with a higher fuse rating fuse ( I know....) to see if the issue would be fixed. And surprise surprise the fuse box got hot with a burning smell coming from underneath, so along with the original fault I also need a new fuse box....
The positive in this is that it is now obvious where the short is coming from as the connector pin is burned/melted.
Does anyone know what is connected to this pin on the fuse box? I think it is pin 3?

Any help is greatly appreciated!

No idea from which year is your Stilo, but have you tried eLearn from the download section here? There are electrical diagrams in there :)
Thanks, that was a big help. The schematics showed that the burnt pin didn't connect to anything in the car... I replaced the fuse box and all is now OK. Must have been an internal short inside the fuse box...
