Gents, wired my 'line lock' thruough the horn from an internet site diagram, all looked ok then a few minutes after I finished mounting the horn button, the horn came on and only went off when I disconnected the horn wire. I check the wire functions and still have no solution. Any similar experiences?

George you need to post your questions in the appropriate sections above, probably Brake and Suspension is best. This is the section for testing out your posting skills, trying to edit your profile and post pics to get the knack of it.
