As it has "HONDA ALARM SYSTEM" on the boxc7u8 , belive me its genuine Honda:bow: , And is specific to the Blackbird. Honda fitting instructions are for the xxw(mine), also has Honda on both keyfobs, I think they only made them for carb model. I have checked my self on the Honda web site too and I cant find it , But I also seem to think that it was a dealer fit only as instructions were worded for the dealer only, I also have been told that it costs around ?300 fitted. So stand corrected :t , but can anyone back me up:dunno: ?.
