If you check the 9-way connector on the right hand side under the tank, you should see a jumper wires between pins 3 (Green/Black) and 4 (White/Yellow) on the switch cluster side of the connector pair. You will have to pull the clear plastic shroud out of the way to look. If so, this is the modification for North American models that functioned to give DLR. You could cut this wire and install the switch there. It would be a cleaner modification.
