Wire the throttle's black connector to the controller's derailleur connector matching same color wires except green goes to blue. Connect throttle's blue and yellow wires to controller's power locks connector and if the display does not turn off when the key is off then reverse the positions of the wires.
The throttle's blue and yellow wires both go to the controller's connector with "key" written on it.
