I  have an old Klaxon 6v round face pancake horn that I would like to put in my 55 Fairlane. The car has been converted to 12v. What gage wire do I need. Do I have to put a reducer. I have a button. Do I need a fuse, what size. Do I wire it up to the Battery or Selenoid. I know this doesn't really pertain to Y Block issues. I've searched on line but can't good answers. Any info would be great. Have yourselves a good FORD day.
