Thanks for ideas...i think i will just fit a button,run to fuse and live,had a look on you tube,seems easy enough...

Horn failed due to clockspring...any techies near Aycliffe county durham ?...already had leccy 'fix' £50 then went off again..now needs clockspring but cant seem to source the right one..need help..mot next month.

Horn not working .. checked fuse and relay both seem ok..what next ?
