I'm about to install (in a crx) a Sard turbo timer I got off a buddy for super cheap, and I plan to just splice into my stereo wires for the 12v (red) and acc (blue) but I was looking in a GReddy instruction booklet (mine are in japanese) and the green wire is for cars w/ a 2nd ignition wire or something like that, do we still use the green wire?

If we do, what wire does it tap into? Also, if you know, what color it is. Thanks a ton
