 I take that head of the crawler, that dark part, and I hook that through the front hook of that harness. I straighten that worm out so there's no bend in it, and I hook that second hook. Normally, that second hook goes right around the band of the nightcrawler. Now, if you've got a real big piece of worm hanging off that second hook, I pinch that baby off so that there's about three inches of nightcrawler tail hanging off that back hook. It's plenty. And what'll happen is you're going to get a higher percentage of good, positive hook sets when that walleye whacks your presentation.
