One of my X5's horns is dead. The one on the driver's side is good, the one a little more towards the passenger side is bad. It look to me like in the diagram on RealOEM.com that I need the Low pitch horn, but given the lack of mounting reference on the diagram it's hard to be sure. Can anyone confirm that this is the right part number:

01Horn, low pitchHELLA 420HZ161338387342$51.48

Thanks!
