04 Horn wire

Does anyone know if the yellow w/green tracer horn wire (this wire is located under the passenger battery tray) supplies positive or negative voltage to the horn?
This is on a 04 F250.

Thanks,
Eric

Found it. That wire is positive. Grove air horns are not work. It goes back to regular horn when the key is off. That way my super deluxe Gold Ford alarm still works.
