hey gusy i have a 1994 Park Ave Ultra with the 4 Note Horns. I got an extra set out of a 1994 Deville to put on my Mercury Grand Marquis LS 2-Door. What 2 notes are the low tone and which 2 are the high tone. I want to put the too the same together. I am guessing that is the way it plays it in the right sequence. Thanks
