Mobow is exactly right. If you want to tie it in you will need a bow press. You just tie it in to your down cable. Mine is tied in by splitting the two different colors of the cable, then placing the whammy string through the middle of the cable. Then i tied a small knot and added a burn ball on the end so the knot wont pull through. You may also want to serve both sides of where the rest rope goes into the cable so it wont slide. After that put the rest on and get the center shot and all of that good stuff then put the rope through the metal trigger part of the rest and then tighten it down with an allen wrench. Some people like to tighten the allen then fold over the access string a serve the two ends together. Thats your choice. I hope this makes sense. If you have any questions feel free to ask.
