Sorry, MandR... my buddy said he threw the instructions away.
Based on my memory (which is awful lol), I believe the activation cord needs to attach to the "down" cable on your bow... i.e. the cable that travels down as you draw the bow. In order to figure out where to serve it in and how long the cord should be, you'll need to preload the rest by hand... then have someone draw the bow back... then pull the activation cord tight down to a spot on that "down" cable, usually this will end up being near the bottom of your bow's grip. While the bow's drawn back and you're holding the activation cord tight, mark that spot on the "down" cable and the length of the activation cord with a sharpie. Relax the bow, cut and burn the end of that activation cord, and serve it into or clamp it onto the "down" cable right where you marked it with the sharpie.
I think this is how it's supposed to be set up... Like I said, this is all based on memory from setting one up almost a year ago, so please don't hold me to it. Good luck!
