bits needed for my new 456

Hello all,
I've just signed up to Ferrarichat because I've bought my first Ferrari, a 1994 456. It drives well and I'm happy I've bought it.

So far I've found a few electrical issues that I need to look into; one window doesn't go down as it should when the door is opened, the heating control system isn't responding properly, and one seat isn't moving forward when the backrest is tilted. I see some threads on these issues and I hope the information will help me troubleshoot the issues. If not I'll be back on here asking questions.

I thought I would ask the forum whether anyone has any of these bits and pieces lying around, because I'm missing them on the car:

- My key is the one with a little light in it. (The part number is 164089, it seems.) My key is only 'half there': it's missing the plastic cover piece and it's missing the light unit itself from the key innards. I find I can buy a new key - for a lot of money! - but does anyone have just the plastic cover and/or the light from a key, by any chance?

- A left (driver’s - LHD car) floormat in blue plus the clips to fix it to the floor.

- One screw from the plastic cover over the engine, number 13302577

- A toolkit

Thanks for any leads on any of these.

 

Yes, I'm in Granada in Spain, and I bought the car locally. It has spent since about 2000 here in Granada, before which it was in the UK for a few years, and before which it was originally sold new in 1994 in the Francorchamps dealership in Belgium. The car is silver with a blue interior and I will see about putting up a picture.

Many thanks for the lead on a Alfa 164 key being the same. In fact I have a 1997 Alfa, a 916, but that has a different, red plastic key, and I hadn't seen this black square plastic key before on any car. I'll see whether I can trace an Alfa key to cannibalize.

Since my car has spent most of its life in the dry Granada climate, my exhaust seems fine, and I don't see any rust anywhere on the car, in fact. My wheels are also more or less spotless, and the body as a whole has only a couple of tiny marks on the paint for its 26 years.

At some point some owner (not either of the last two owners, with whom I'm in touch), did not hand on the toolkit with the car, and that is the most obvious 'missing piece' that I'll try to replace, although of course it's merely a case of having the car 'complete', rather than being of any practical importance. Am I right that the 456 toolkit ought to have '456' written on the leather?

Over the christmas period I intend to play with the electrics to try to sort out the little issues that are of importance: see whether I can get the heating/air conditioning working, the passenger window to go down when I open the door, the central locking to work, and the driver's seat to move forward when I tilt the seat back.

I appreciate all your replies, thanks
Julyan

 

Thanks for the information. Here is my car:

Do you know whether it's useful for me, having just bought this car secondhand, to register myself on the myferrari app and add the car to it? Does the myferrari app give me access to anything useful as the owner of a secondhand, 26 year old Ferrari?

I'm not sure whether I should ask this here or should start another thread, in another area of the site...

Merry christmas, Julyan

 

Owners manual: I have the leather pouch with the owners manual, service book, list of dealers, hifi manual etc. My owners manual is 792/93.

I also have a copy of the workshop manual, which I'm using to troubleshoot the electrics.

MyFerrari: I have tried registering twice, with two different emails. It takes my data then when I come to login it says "Sorry! Dear user, your credentials are no longer valid for accessing the MyFerrari portal." Perhaps it's a christmas problem of their server.

 

Sorry, I should have been more careful in my reply. I have a workshop manual for the 456, and for the 456M, and, yes, I see that it's only in the latter that there's a wiring diagram. That explains why the previous owner had the manual for the later model, and why he passed it on to me along with the correct manual, which is something that puzzled me at first, since as far as I know, he had never owned a 456M.

 

I have the two workshop manuals, but not that expanded section L, which sounds like it could be really useful - could you point me to somewhere I can find it?
Thanks

 

Many thanks for that, Ian. As you say, I'll have to see how much is useful on an earlier 456.

The little problems with my car all seem to be electrical. I have it down in the garage with part of the carpets and door cards removed to expose the innards. So far, I've removed an old Clifford alarm - I didn't even have the remote - and am tidying up next to the fuse box where the wiring was cut to insert that. Apart from that, there seem to be two issues:

One is that the central locking doesn't work and nor does one of the door windows lower when that door is opened. Removing the door cards showed the problem here - someone has messed with the wiring. The window doesn't lower because that control box has been removed. And it looks like part of the wiring has been disconnected that is probably the central locking. So I'm trying to work all that out. If anyone has pictures of the doors showing the correct wiring and where everything should plug in, I'd like to see them. I see that a control box is very expensive, but the actual electronics is almost certainly very simple; I don't suppose anyone has made a circuit diagram or a replacement circuit?

The second problem, possibly not linked to the first, is that the heating controls don't work. The previous owner had tried to fix this and had bought a replacement heating control box. But neither the old nor the new box makes anything work. I'm trying to see where I might start to diagnose this one. Any tips will be gratefully received.

 

I meant that so far I haven't managed to get the heating controls to respond at all. But I'm not familiar with how they should work. If the AC switch is off, should the fan run? Or does 'off' mean absolutely everything of the AC, heating and ventilation is turned off?

Regarding the door electrics, here is a picture of my left-hand door after I have taken the door card off. What is that connector above the control box that is not connected to anything? Should it be there or is it another modification someone has made for an unknown purpose?

Thanks for any help!

Yes, it plugs into the other side - thanks! It does look like the wiring has been messed about on this left door, because the connectors look as though at least the harness has been unwound, but it's the other, right door where things are definitely bad. There's no box, there and the connectors have been removed and the wires joined 'ad hoc' in some way to kind of make things work. I think I want a box and a wiring loom for the right door.

A question about the box: should it control both the window mechanism and the door lock mechanism?

 

Thanks - I'll check this tomorrow.
