can some one help me make heads or tails of this diagram? took me a long while to label out and follow each wire to its location on the pcb, basically I'm trying to figure out what XS, SH, SL, SD, mean in relation to each other. There are 2 extra connectors on my very generic control unit that I cant figure out, I believe the 3 pin is PAS, but cant be sure. And then there is a 4 pin which I have zero idea of its function, but I think it has sumtin to do with the brakes since SH is connected to SL...

I don't think this controller can support a display since it lacks the TX and RX pins, but is there a way to connect a PAS level selector to this? or is there a way to activate regen braking if I connect the X and DS pins? if so how do I connect it up after I bridge the pins?

scouring the net has taught me as much as this, any more and I need guidance which is why I'm here now :?

thanks to anyone that can guide me in the right direction :bigthumb:
