re: "I wonder if the speedo cable’s routing was so far out of line that
it needed a slight short cut to achieve its destination. My cable goes
through a grommet to the left of the bottom left corner of the control
box. Is that correct? Or should it take a more central route?"
Disclaimer: I've not owned nor worked on a RHD car.
Since the speedometer gearing is on the left/port side of the O/D
housing--unless RHD cars are different--on a LHD car the cable has to
make, in effect, a 'hard' 90deg left turn. Yet, besides the occasional
glitch speedos in LHD cars work, well, OK (what matters is that routing
isn't so drastic as to kink or bind the cable). I can't see any purpose
for the optional hole as the speedo cable would make a more graceful,
easier turn to the right in a RHD car. My LHD BN2 has its cable just
wedged between the gearbox cover and the scuttle, unless I installed it
wrong.
I can't imagine why /any /speedo cable would need to go through the
scuttle/firewall, if that's what you mean by 'control box' (aka voltage
regulator). Mechanical tach cables have to, though.
