Sorry man, i don't know too much about helicopters...
Just FYI, there is a relay box for the rear window, it is located in the stupidest place...behind the driver's door in the side of the truck.
I just wired a heavy 30amp center-off momentary rocker switch (on-off-on, DPDT) to the motor in the rear gate, just have to be careful not to put the window up when the gate is open or the top is off.
