To get access to the cable connections inside the switch housing you first need to extract the on/off button - there is a slot down the side of the button housing which is intended for a special-to-type tool which releases the barb on the button when it is pushed down the slot - it's not easy to get out!
If and when you get the button out you will then need a torx screwdriver to remove the screw which holds the switch assembly in place.
When you have got this far, the rest is a breeze!
