Would like to keep my original headlight switch. Have truck all converted to 12 v. With the switch handle 12 v? If so any have a wiring diagram for it? It is marked battery and horn on 2 spots but no other markings. Thanks for any help. Bill

I don't know about the terminals on your switch. However your ignition switch needs to turn the ignition and gas gauge on and off. The horn would not be switched. You can use an ohm meter to see how the switch works and go from there.
