Elec Window intermittent Help

2002 Octavia estate - osf drivers window failed in down position, changed motor no improvement, regulator looks ok,  When door stripped noticed that loom had been worn through to wiring due to movement of regulator.  Jiggled wiring and switch worked window up and down but then failed again  - I think there may be a broken wire but need to know which wires link through from switch to the motor.  Any help appreciated!
