Remote Start Question

I'm installing a Viper remote start on a 2001 Golf 1.8T. According to the instructions I am supposed to splice into a tachometer wire (color = green/stripe) at the ignition coil. Well this VW had 4 coil packs, none of which have that color wire in them.

Does anybody know where I can find the tach wire on this vehicle to make the remote start work?

Thanks!!!!
