2012 - Factory SurfGate Control

[Setter]

I recently had the MaliTouch screen to the right of the steering wheel replaced. The new one came with the software that has the surfgate control in it. I am in the process of making my own surfgates. I am intending to use the Arduino setup to control it. I know that it wont be as simple as just hooking up wires but can anyone tell me what it would take to control them through the screen? Is it a whole new control module, wiring harness, relay module, or even more? Even if I was able to just use the onscreen output as the Toggle switch and still had to use the Arduino to do the actual servo controlling I would be fine with it. I'm sure this is a harder task to accomplish than I hope but figured I would see if anyone has info on it. If it is possible would anyone be able to get part numbers and or price to go with it. Thanks Again
