A lot of people wire theres into the ignition coil I know that much. Where exactly into the coil, I'm not so sure.

99-00 LS1: Tach line is Pin 10 on the RED connector. Tach line is a white wire

The switched side of the ignition coil is where you want to pick it up. But i don't see the point of running a wire all over your engine compartment. IMO, much cleaner to pick it up at the PCM locations listed above. And yes, i just quoted myself,

Pre 96s should be able to use the white/black stripe wire to the coil if you don't want to use the tach wire.
