Any one know what this is?
We just bought a 58 T Bird. Under the hood is a silver box with some electronics in it including a rheostat, that can be adjusted with a screw driver from out side the box. There is, what appears to be a lamp cord type wire, going to the inside of the car, to a push button. The previous owner had no idea, and said he never pushed the button. It almost appears that it may be some sort of after market horn. That's just a guess.
Can anyone help here?
Thanks,
Ken
