I believe there's a constantly hot terminal on the ignition switch which
you can use for this purpose (at least there is on my '69 model, which will
have a different ignition switch configuration to yours) - I can't remember
which one, and I don't have my Bentley's at work (although I should just in
case something goes wrong).
You could just probe the terminals with a multi/volt meter (with the battery
connected of course) to find out which one. Then again, someone on the list
may have memorised the terminal configuration of the ignition switch - you
never know your luck.

I haven't done this but it sounds easy enough, and a sensible thing to do
too.
The PO of my TR6 had installed air horns and thrown away the stock horns,
which I suppose is fair enough. Unfortunately, and this is where he earns
the "D" prefix for PO, he had also not bothered to use the centre push
switch on the steering wheel for the new horns, but instead installed a push
button switch in the centre console *behind* the gear stick - a very
inconvenient location indeed. You should consider yourself lucky that
you can actually find your horn switch *before* the accident happens :-)....
Must get around to fixing that someday, and the fuel mixture, and the valve
guides, and the paintwork, etc...
