Munch,
Is that a flaming river column? If so, the cancelling cam (black disc that goes on before the wheel hub) is just not in the right spot. I had an issue with a steering wheel adapter hub I was using. The hole for the horn wire was in the wrong spot and did not allow the cams to be in the correct location. I believe the horn button wire needs to be in the 11 o'clock position if I remember correctly. Once I elongated the hole and the cam was in the right spot no more issues.
