There is a - signal wire on the coil wires.that the green must be hooked to. Without looking at an actuall wire diagrahm I couldn't tell you which one. Other than it's the same one I tap into when installing an alarm with remote start feature. Any metal or even the ground for the head unit will work....... Same for the power wire for that matter cause the deck should only turn on with the key.
