If i remember rightly, i could be wrong, i am sure the fusebox is inside the passengers glove compartment, i think you have to unhook the bothsides of the glovebox to get to it.
open the glove box theres a black plastic panel at the back it lifts out sort of ovel shaped nice of fiat to hide it there then tell us in all the manuals its somewhere ealse
Oh, Thanks guys - It has been driving me nuts - according to the Fiat Manual, it was supposed to be under the steering column. But there again it was printed for a left hand drive.
