wire from tt. were does it go

[srt4driver18]

on my greddy tt. i have a greywire and i don't now what it hooks up to. the directs off srtforums.com doesn't tell u were it plugs into. and the directions that came with it are all in japenese.

were does it go

if im correct the grey wire has a connector on the end? if that is the one then you dont use it, just zip tie it away and i would put some black electrical tape on the end. but anyway yea even in the american version of the book it tells you to not even use it, it has something to do w/ japanese cars only.
here is the link for the american directions. look under the optional set-ups section and look at the pic.
