No, I've got the TR style- not sure if they changed to cable for TR6, but
it's a bunch of cross shafts, bellcranks and ball joints that somehow get
your foot movement to crank over the throttle openings.
The North American TR6 has the same set of mechanicals to operate the throttles.
The RHD PI TR6 uses a cable running from the throttle pedal directly to the
throttle butterfly shaft on the intake manifold. Pretty simple setup with
little play in movement.
