Can someone please tell me if your horn sounds when Smart is off? I was messing with my stock horn, pulling the wires ect, and noticed it only sounds when Smart is in acc or on mode.
Yes it only works in on position. Also the blue and brown wire have to be connected properly to work.Use search option to look up "horn install" for a lot of good info.
I installed the Wolo compact air horn made in Italy.Think it's same horn as yours with another brand on it.Found it for $22.99 on clearence at auto zone.Try this link for install info.Tutorial: Replacing the factory horn
