I've fitted a rather nice steering wheel to the old car which comes with a
horn push in the middle. At the moment the horn is activated by pushing
the indicator stalk. It would be nice to have the push work as well - but
of course this is usually achieved with fairly involved wiring either up
the steering column or with slip rings.
There's a fair amount of room inside the steering wheel boss, so a
battery transmitter and 12 volt receiver elsewhere would be nice. Anyone
seen such a device at a reasonable price anywhere? All I've found are IR
ones.

An interesting idea, these are a fairly standard module:-

At one time RS used to sell them, I'm not sure if they still do.
