Good morning. Again I ask you to bear with my lack of knowledge. I looked at Wiki pages and read about blue/black wiring to horn and brown ground wiring. I realized there are no wires coming out of my horn. I am attaching some pix- could the covered wires I am holding be the wiring I need to plug into the horn?
Also is there a way I can hook up the horn to an old External battery just to test if it is working? If so, what voltage battery?
