These are the connectors I was talking about.
http://www.radioshack.com/product/index.jsp?productId=2104016&cp=2032058.2032231.2032283&pg=2&parentPage=family I'm not sure if the connectors need to be 1/4" or 3/8", but you could just take the horn in to a radio shack. So on each of the female connectors going to the possitive terminal on the horn, you'll want 2 wires crimped. My horn is currently out with the wiring attached... if I remember when I get home, I'll snap some pics.
