If you did not get pizzaguy's file...you can get to the cable routing by removing the fender liners in the trunk. You will need to take off the liner at the back, where the trunk light is, first then the fender liners can be removed. There is 6+ push pins that hold them to the fender. Threre are zip ties that hold the cable to the tonneau arm, as I recall, then you will see where it connects to the respective hydraulic piston. They are the same on connection and routing on either side. You will also have to unbolt the cable connection from the tonneau flap when you replace them. Take pics as you go so reassembly is easier. Good luck!
