JeepGirl and Harbor Freight to he rescue. For my birthday she got me a set of air horns. I hooked them up last night. I fished the wire from the driver's side horn back into the engine compartment. I hooked it to the positive terminal of the compressor which I mounted where the air box used to be. I had to add a ground wire from the compressor to the body. I stuck two of the trumpets through the hole where the air box normally breathes and let the other trumpet rest under those.
Now I have a real attention getting horn.
