GT Veloce wiring and console control issues

[JHertzman@domain.elided]

In AD7-1138 Emmo, and in AD7-1039 Bob Brady, discussing a 1750 GTV dash into 
a 2000 GTV, correctly emphasize that dashboards and wiring harnesses are 
Siamese twins, joined at the connectors. I once contemplated replacing a '78 
Sport Sedan dash with the more traditional-looking '76 instruments, (which 
use the same pair of eight-pin connector blocks) and more recently have been 
looking at transplanting a 1750 Berlina dash into a 2000 Berlina, and 
wouldn't try any of the three swaps without moving the wiring harness along 
with the dash. It might be possible, but it would be a very formidable task. 
In the case of the '76-'78 sedans, both used identical block connectors for 
the circuit board integrating the instruments and warning lights, but used 
entirely different pin assignments; mechanically plugging it together would 
be deceptively simple but the resulting circuits would have been garbage.

Bob asks whether someone can confirm the later reliance on major multiplug 
connectors and the earlier reliance on lots of single wire connections. By 
the parts books, the 1750 GT Veloce used eight block connectors of five 
types; the 1750 Spiders used fourteen block connectors of nine types; and the 
2000 Berlina used eleven block connectors of six types. Most of these are 
just convenient links for wiring modules, but the wiring diagrams on the 
Owner's Manuals clearly show the integrated instrument clusters (and related 
wiring) of the 2000 Berlina and 2000 GT Veloce, and the separate instruments 
and warning lights (and related wiring) of all of the 1750s and of the 2000 
Spiders.

Bob goes on to ask about the console-free layout of the 1300 Junior, 
referring to hvac controls and switches, and asking Scott Fisher (or any 
other Junior owner) for answers. Scott's reply, referring to "the 
(fiberboard) dash" sound as though he may have had the earlier Junior and not 
the one Bob was thinking about, and anyway I expect Bob is talking about hv 
controls, not hvac controls. Juniors came with several dashes; the original 
fiberboard and vinyl "wood" of the stepnose, the basic 1750 dash with a small 
pendant panel for the heater controls and two gauges, with the three console 
switches relocated to the left end of the dashboard, and the 2000 dashboard 
with a slightly simplified version of the full 2000 console. There are 
reasonable pictures of the three on pages 606 and 608 of d'Amico & Tabucchi.
