Just got this off google There are two wires that go to the auto box's selector box. You need to bridge these two wires for the car to start if you have stock ecu. I didn't need to do this step as I have an aftermarket ecu. After everything is connected up you should be able to ride off into the sunset happily, and in full control of when you shift.
