Get your nuts and bolt and some small fingers. I slipped a rubber washer between my Cowl and my frame just for good measure.
They go in right above the rectifier. Pretty easy, than I zip tied mine underneath. I used METAL ZIPTIES from home depot. I get some COLD weather here on occaision and I didnt want the plastic ones to break. I havent had luck with those in cold weather on other things. They thread on real easy cause you can bend em to wrap around whatever. Thing is, you need a dremel to take em off. Either that or a LOT of patience.
Works nice.
