Another gauge question... Where do I wire the tach?

Hey guys, I hear the factory tach is horribly innacurate.. so I bought an Autometer 3 7/8" sport comp tach. I'm going to install it on the steering column, covering up the factory tach. My question is, power and ground I can deal with, but where do I get the signal from? Thanks guys!
