I have a 1000 watt 48v brushless controller that came with a twist- grip throttle controller. which has three wires feeding the control box( ESC) . The thumb throttle that I purchased has 6 wires coming out of it. The thumb throttle also has 3 led lights on it. Green, yellow, and red I guess to show what position your thumb drive is in, like low, medium, and high. The kit also came with an LCD display that shows speed and battery level. I don't think I need the other three wires from the thumb controller but I was wondering what they are for. Also, I notice it has a red button on the thumb throttle which is maybe for a curse setting?
