Paul, check out the diagram at
http://www.zeni.net/trf/TR6bluebook/83.php
It shows both the plug you are talking about (ref CL27), and the switch that
goes in those holes when you have overdrive (ref CL32).

There are a very few other examples of metric threads on the car, like the
studs that hold the instruments to the panel. Believe it or not, metric
threads were defined as early as 1898, but the British car industry (much
like the American industry) was slow to adopt them.
There are also a few examples of obsolete (even then) British Association
threads on the car, like the carb fittings and the "Lift the Dot" studs
(with machine threads).
