wiring diagram for 456M

I'm looking for a wiring diagram, not a block diagram of harness and plugs, but a real circuit to circuit type schematic. I've downloaded section L of the workshop manual but not what I'm looking for. Perhaps they didn't make them available?

A bunch of stuff.

Jack, you might have a look at the 550 WSM and its wiring diagrams. Sometimes it's helpful, as are the wiring diagrams from the 355 manual.

I usually start the electrical diagnostics by trying to get my head around what they were thinking (and sometimes THAT'S a real challenge) then I break out the DVM and start the point to point process.

'99 550, Rosso Corsa / Nero, S/N:114654, Assy: 31836, Engine: 52084

High mileage, low compression, and missing on a few cylinders.....just like my cars.

Thanks John I will look into that and we think exactly the same, I normally have to have a list of the color identifiers in BIG print so I can reference when tracing.

Jack- I sent Ben Deetman an expanded electrical section for the 456M that is online at ferraridatabase.com. That has really good section by section diagrams for all the major and minor harness connections.

Dear All,
I have found above old discussions about the 456 wiring diagram. I own an 456GT from the year 1995, so it concerns the first serie. I am also in need of an colour wiring diagram. I have already the workshop manual with the mentioned section L included. I need a similair diagram as P2164 is talking about. I am located in The Netherlands. Can somebody help me?
Thanks in advance, 456gt

There are expanded section Ls that were available separately from Ferrari, but I have only seen the one for the 456M, not the 456 GT. 80 Mb, so too big to post.

Dear Taz,
Thank you for your reply. Can it be that the diagram for the 456M is quite similair as for the 456GT? Can you send it to me by personal email? Perhaps it can help me any way.
