I believe it was fitted to some cars, possibly even required in certain
markets (Belgium ?).

Sounds like someone has replaced your gearbox (or at least the top cover) in
the past.  As mentioned, you will need to either tap your top cover for the
switch, or find one already tapped.  

If memory serves, the reverse light switch on a TR4A would be in the top of
the cover, over the reverse shift rail.  Should be a boss there where the
switch goes.  The tap required is an odd metric thread though, not in the
usual sets, so you'll also need to buy a tap for it.

Later cars had the reverse light switch on the side of the top cover, but I
think they may have had a modified reverse shift rail as well (with a hole
for the switch plunger to drop into).

FWIW, a TR250-6 top cover should work, if you can find one with the A-type
switches on it.
