I now managed to receive a wiring scheme for my controller:
I hope some of you can provide feedback to the open questions which come up after I have seen and tried to understand.
The following questions:
* I already know that connecting the two grey result in lower speed, very low speed----like 15km/h.
but what does the brown/white low speed signal and brown/red high speed signal mean???
maybe you have similar features in other controller.....this connector is open in my case and not connected anywhere....
* does anybody understand what green/blue display means??
* and what does the purple electric door lock do?, how does it work?
Thanks, really curious to hear and read from your feedbacks!
