Tach

Hi, I have a 2001 Chevy Express 1500 5.7 Liter. I was wondering if anyone has hooked up a tach and how they did it. I have installed a tach before, but it was on a car with a coil and distributor. Do they make adapters that hook up to the plug wire where it connects to the coil pack? I wanted to put a tach in and was wondering how to do it. Thanks, Tim
