Hello everyone, nice to be in this forum. I am new to ebikes and am looking forward to doing more with them. I want to change the thumb throttle on my Brawn to a half twist. The problem I am encountering is the thumb throttle on the bike has a auto on/off switch for the headlight a photocell I geuss I don't really care about that, I don't use it since it will turn on the lamp when the bike is off. So what I need to know i which three wires are for the throttle. Most throttles I have seen are three pin with a yellow connector body. I am planning on severing the wire and leaving a pigtail on the green five pin connector and splicing in the new throttle. Does anyone know which three wires are for the throttle control? Thanks you in advance.
