I am opening this one up again in the hope there is more information.
I also have a 1986 +4 with the Fiat 1,995cc Lampredi engine, and would like to have a wiring diagram. Having looked a lot, I cannot find anything appropriate.
Also, does anyone know where I can find a manual on the engine and gearbox? I have asked the MMC and await a reply. Fiat owners advise that the Fiat 132 has the closest engine, but they also say do not use a Haynes manual as they have misleading information.
