For everybody's general information..
Below sketch explains why intercepting the Pink wire at T122 is better than pulling Fuse No. 7. I traced back what else gets deactivated by pulling the fuse. As we can see, it both disables the rear brake lights and signalling the ABS actuator control unit.
I found out the other end of the
pink wire terminates at terminal 3B of connector M2 of the driver side Fuse Box. I find this very helpful because it's much easier to intercept the pink wire at Connector M2 than on connector M107 of the ECM. All I needed was 30cm of 2-core wire running to a switch that I conveniently placed on the trim panel underneath the steering column.
