See the reply I got below...not very promising. Anyone interested in being the first guinea pig?
"Dear Sir/ Madam
Thank you so much for your e-mail. My name is Tsuyoshi from Japanparts.com. About 415-014-020-1, it is for A/T, so this is okay for the transmission type. However, all of our parts are basically for JDM, so I can not guarantee that this will fit to USDM.
Also, the installation directions in English are not available and not able to check the signals, so I can not tell that this sound is same as the US signals.
I am sorry for the inconvenience.
