So my wife LOVES to honk at people, so I thought about installing a little surprise for her and put a set of hella horns in for her. What I need to know is the best place/way/tactic etc to get these attached. She has a 2011 Pilot touring. I've read that I'm going to need to wire them to the battery, but I've also read I can use the existing connection for the stock horn. Any advice would be appreciated.
