you simply run the cables from the back to where ever you are terminating at the brake pull... they give you PLENTY of cable - IIRC I measured the distance from the furthest point I expected to need to get to and added 30%.. I have a hand pull Ebrake lever that I mounted on the floor next to the drivers seat between the door and the seat.. the drivers side cable is WAY shorter than the pass side.. I will try to get a pic or two of it later
