get a photo of the connector
depending where it's been made the trigger wire could be any colour.
does your head unit have rca output or are you going to be using the hi leave speaker outputs?
is that a extension cable that plugs into the original wiring if so check if the blue wire is connected to anything if not I would think that would be your switch wire
if that doesn't work let me know what head unit it is and I will check a friend of mine who does that stuff for a living
