Hi,
as far as i know spare wires hanging around is not usual car design. What can be is that wire harnesses are built in that provide wiring equipment for facilities which are not built in every car.
If you have no pugs sockets and wires hanging off your car its not actually a Fiat.
Probably Audi or BMW they are so boring they dont have character things like this to keep the grey cells growing
which is why the drivers of said thngs drive as if in a cocoon in a different dimension quite a lot of the time... Love.........
I know what you mean. But I seen online some time ago, that some manufacturers installed the wiring to accommodate if they were installed at a later date.
