The wiring kit is all you need. Use the horn bracket and AI pump bracket under tank to attach relay. The horn will sit high enough and far enough from the oil cooler and will not impact its cooling ability. Horn works great. Similar to the hand held air horns you buy in a can. I snuck up on a couple friends of my wife who were walking on the road when I gave the horn a quick burst...they are not to friendly anymore :-) !!
