The_Mask_of_Vulcan

yes, there is an old thread that I made on this subject. You can see it at this link: http://www.vulcanforums.com/forums/s...ad.php?t=13241
I was able to do this because I installed the thunder air kit, this way it's out of the weather and sounds just as loud. You cannot use the factory wiring for this horn. Yes you will need to take the tank off and run a heavy gauge wire to the relay that comes with the horn. I did use the factory wiring to the stock horn to trigger the relay. A diagram comes with this to show you how to do it There or other threads that show pictures where the horn was mounted where the stock horn is. Just do a search on air horns and you should find them. If you need help just let me know.
