Just completed this job myself, unfortunately had no instructions so had to learn all of this the hard way. I carefully re-wrapped the cables then used a bolt, washers, and a nut to clamp the cables together for instalation, this holds the cable in place on the drive pulley/drum. I then routed the cable on the door pulleys until the last pulley, held the cable tight and removed the bolt that clamped the cables together, and then routed the cable on to the last pulley. I did not replace motors just cleaned and greased everything and the window works much better, not fast, just better. Be very careful when winding the cable on the drive drum not to cross the cable as it winds and retracts, it will bind and possibly brreak something. Good luck.
