draw all the pulleys on paper about 8 times or so, then draw all the possible ways the belt can go, try 1 or 2, then you might be able to eliminate 2 or 3 more looking at the diagrams on paper. then try the rest until you have it. it sounds hard but it really is pretty easy because the wrong routings youll see after routing around about half the pulleys cause the length will be so wrong already. i did it on a ford i was repairing for someone in about 15 min.
