Starting with the second generation of DL1000, the speed is determined by the ABS wheel sensor information sent to the ECU instead of a dedicated speed sensor. There is no longer a speed sensor connector to separate and plug a speed adjuster device into. The pink/white wire that feeds the speed information from the ECU to the display has to be cut to provide the speed signal from the ECU into the SpeedoHealer or SpeedoDRD and that device then feeds the adjusted signal into the pink/white wire to the display. The four wire device also needs to connect to a black/white earth wire and a white/green switched power wire so you have power, earth, signal in and signal out handled.
