Sweet! Nice job finding the basic control concept.Thanks for the offer, but I already found the solution, and I feel really stupid.
All you have to do is put grey and white into 5V and GND, depending on which you put where it steers in each direction.
But the important part is to use two different power sources for red/black and grey/white, or nothing happens.
So it does indeed look like I need a H bridge, but I wonder how I should organize 2 power sources, and which voltages they need...
I know you said the remote to the control board doesn't work, but can you power it up at all? If you power it, do you see power on any of the wires that go to the servo? My guess based on what you've said so far is that you won't find any voltage between the white and grey wires, but if you're lucky, maybe you'll find some voltage on the red and black. If so, you'd be one step closer to picking voltages.
