using a Lyen 18fet and Tektro ebike brake levers. I have just one pair of wires from the controller yellow and black. So hooking up two of the brake wires from each side together and only the right hand works . I tried other brake levers I can only get the right side to work. Yes I flip the wires many different ways many different times. My left brake works backwards. Can I only use one lever ?
