I've got a 71 grabber with a large "cylindrical", cannister-type object mounted opposite the drivers side horn (uses the same mounting bracket) toward the front of the wheel well. It faces the front of the car. There is a wire attached to it that goes to a button that is kind of just hanging under the dash. Another wire comes off the button, but it has been cut. Anyway, I put 12 volts to it and heard a scratchy "aaahhooogaahhh". I got a 72 parts car when I bought this one, and it has the 72 owners manual which lists "Air Horn" as an available option. Does anyone know anything about these? I'll try to get a couple of pictures later today of the horn and button if someone might know what original stuff should look like. Maybe someone added it later, but the mounting looks pretty "clean"...and it's about as crusty as everything else on the car as far as road grime, etc. I did a search of the posts on here and didn't find anything. I didn't want to start a redundant topic.
I don't know a whole lot about the horns but i believe that the horn buttons are activated when the ground is broken rather then the circut being connected like your regular switch
air horn an aougha horn on a maverick stock...never heard of one, although I have hooked up a couple of aftermarket ones.But, you never know.
Horn In 1973, when I got my drivers license. I went to Kmart and bought a fm stereo 8 track tape deck, 4 speakers and a aahhoooga horn for my '64 Fairlane 500, 289 2V V8. The horn was fun, there was no mistakeing who was comming from a distance. When I sold the Fairlane in 1974 for the Maverick, the guy wanted the horn! I kept the tape deck. I still have it! As for the horn being factory equipment; I don't think so. Mabe a dealer item but I dought it. They were sold at department store, Auto supply stores, tire centers. The Plymouth Roadrunner had a horn that said Beep/Beep like the cartoon! That was factory. Joe
I have a 1971 dealer brochure and there is no mentioning of any optional horns. Although I dont like to make definate statements cause my foot taste like dirt, I'm going out on a limb and say this was not a factory horn. Maybe a dealer installed it for a customer. The horn is grounded through the mounting bracket. 12 volts is looped through the column and horn button, and then directly to the wire attached to the horn. No relays.
I've seen pictures of UFO's clearer than these, but they're better than nothing I guess. My garage isn't well lit and this crazy digital camera has some kind of night vision, I think. I borrowed the camera from work.
This photo shows the regular horn mounting bolt. The bolt goes all the way through a bracket on the other side of the inner fender that holds the air horn. The wire hanging there is connected to the air horn.
My 1973 owners manual lists air horns avaliable, as well, as a dealer installed option. It looks almost the same as the one in the 72 manual. I can scan it if you want.... -Corbin
