No cable for the tacho, only the differing speedo drive. Again, the later cable has been used to drive earlier Veglia speedos. Hmm, it occurs to me now that you could retain the later light console with no wiring or lighting changes and only install the gauges themselves.
Since your 2002 LeMans would already have white-face Veglia, you are looking to put Veglia on the Nero Corsa? That would look magnificent, IMO!
