Gus Follow the wire for the air horn motor. It is inside the tool compartment and follows the wire harness all the way to the positive bat post. I think it is yellow. In order to get to it, you may have to drop the window washer housing. By the way it dawned on me that I never mentioned how to get the surge out of the cruse control. (A year late, I know) Take the slack out of the cruse control throttle linkage wire. There should be just the slightest amount. Harold McElraft - 3354
