This is my first post on the forum having recently joined after owning my first TR6, a 1971 PI in red. Anyway the horn doesn't work and when I took off the centre horn push there is a small nut in the centre and tfsts it. I think I need a metal plate or wire to connect it to the small shaft that sits to one side of the wheel retaining bolt. I am no electrician but tried to connect said nutcwith said shaft and got a beep of the horn when pressing the centre whilst grounding the side ring onto the wheel. If you could help me that would be great
