if you have a manual for your bow, you should have the string/cable routing pictures. Just follow that and make sure which cable is up and which is down where they cross each other. For the twist of the string/cable, too many or too little are not good, you need to test and try to make sure your bow has the factory specification again such as max draw weight, brace height, ata length, etc. It will take longer time than you think to get it right when you do it at the first time.
