    WOW, I have been following this thread since the beginning and I am praying to the Ferrari Gods I don't ever have to experience this, this is mind blowing. Glad there are so many other owners that have the electrical knowledge and can help out.

    Ok, that's as expected!

    Now you can try to remove this double wired pin (spade) out of the connector J. If i am right it is secured by some barbs (púas). After removal of the pin reconnect connector J to the fusebox. You can leave the removed pin hanging there but be shure it won't touch anything. Now you can try if fuse 17 still blows, I expect (hope) not :)

    That's good! Now all should be fine except for the fog lights, license plate lights and a few check panel lights. Is everything working again including the headlights? And does your check panel work?

    Everything works but: fog lights are disconnected and license plate lights too from the boot connector. Also the P light still appears instead the one that corresponds on the panel behind the steering wheel.
    Check panel works but yellow light is on showing some mistake

    I mean: the Parking light comes on instead of the headlight indicator light on the panel behind the steering wheel.

    Parking light indicator instead of headlight indicator can give us a clue (i have to find out what the cause is). The foglight circuit does have a switch, indicator light and it is connected to the mileage unit. This is one of the circuits with possibly the short. Maybe there is a connection with the wrong parking light.

    What is the "panel light", is that the backlight of the instrument cluster?

    Panel lights are all the panel lights from the instruments, rev, speed, and the central panel…still not working

    What do the pink wires belong to?

    The pink wire belongs to the fog light circuit and the fog light indicator.
    The pink/yellow wire belongs to the license plate light and the check panel.
    In one of those circuits contains a short which is causing the trouble.
    Unfortunately we can't disconnect both wires from each other without cutting them :-(
    So we have to look at the fog light switch first to see of the short to ground is there. Disconnect the fog light switch an measure the resistance between the loose wire of connector J and ground.

    The panel lights seems another issue because they are feed by another circuit.

    I read your first post again and you mentioned side lights. They are not in the diagram so they may be part of the foglight or license plate light circuit!

    Before looking at the fog switch it is better to take a look at all the side lights and measure the resistance of the lights to ground. If you find a short, they are part of the circuit.

    In that case it is good to take a look at the side light connectors and the cabling to see if there is some visible damage. Maybe you can disconnect all the side lights and measure again the resistance of the loose pink wire to ground to see if this solves the short.

    Have tested them now reconnecting them. They work perfectly well with the indicators

    Yes that would be nice :)

    What we know:
    1. There is no problem in the fusebox.
    2. Only one connection of connector J has a short circuit.
    3. The short circuit is either the foglight or the license plate light circuit.
    4. The short is not in the external foglight wiring from the fusebox (we did a check).
    5. The short is not in the license plate wiring in the trunk (is disconnected).
    6. The side lights are probably part of one of the circuits.
    7. The parking light indicator works as a headlight indicator.
    8. The instrument backlight does not work.

    Next thing to do is to be sure the side lights are all disconnected (I think all were disconnected). If they are and there is still a short measurable (pink cable) then I would:

    1. Look at the fog light switch. Because this switch is also connected to ground and is wired to the indicator lights. Disconnect the switch and then measure the resistance to ground of the pink cable.
