If I am not wrong, it is the Comsoft Slim Fix diagram. I installed that a few days ago. You have to use a sharp object to cut it. A razor will do. I used the tip of the tweezer to poke at the track till the connection isnt there. To make sure its really disconnected, you can use the multimeter to check for connection between 2 points L1 and L2. After cutting, the 2 points shouldnt be shorted.
