Ahhhh - I think most horns are wired to work with ignition off. What are you trying to do? Is original horn broken (my guess) and where was it? Center of steering wheel or end of say the directional or something? I forget those cars you needed a shoe horn to fit into already

tyre lever helps to get you out..... the horn push is in centre of steering wheel, and will not work with the ignition on ..... were is the sense in that

I have to do some wilder than my usual guessing now. You say it works with ignition off suggests the button on the steering wheel works which would otherwise be where I would look but not yet.
Most (much more familiar with N. American stuff) you were adding ground by pushing on the center of wheel or to the sides.
They had constant battery power and a relay that almost never went bad but this thing is old enough for anything.
I guess since that's what I'm doing is to find the wiring where about everything that goes up steering column has a plug and check for power to things when ignition is OFF just back probing the connection to see what is powered that cuts out with ignition on to at least know what wire to chase and hopefully remains the same color.
Still guessing that ignition switch would have the wire also and do some hunt an peck to see if it drops out there.
Model year 1973 sold to the US and probably Canada was a year of some changes. I knew these as Spitfires or maybe Sprites and later a TR6. '73 would have a 5MPH bumper, seat belt buzzer if not fastened that would never quit and hazard flashing lights that might not be on the column but the seat belt knew you had the car ignition on and were not bucked up.
They probably wouldn't waste the money for cars not destined here for that stuff so wiring would be unique.
I'd be looking for a fault with the ignition switch. Here would be key on the column, there or elsewhere might be on dash?
Anything altered or if some anti-theft something is involved that would make horn go off would be highly suspect. If taking this on yourself you may need to dig up some precise wiring diagrams for this car for where it was to be sold new OR lots of good educated guessing and testing IMO.
You may need as local automotive electrical specialty shop unless you are capable of properly putting in an entire aftermarket momentary button and willing to do that just for a horn and disable any wiring in use now as it's gotta be wrong/broken somewhere but could be harmless except for this. I plain can't know.
One tricky car maker electrically for what I knew of the ones sold here. Good luck,
Tom
