Helpful:(I dont remember all of the labels used, but using a multimeter will help you)Green/Black/Red wires = Rheostat/ ThrottleRed/Blue wires "power lock" = on/off switch *WILL NOT RUN IF THESE ARE NOT JUMPED/SWITCHED ON*Yellow/Black wires "Brake" = Input from brake leverRed/Black wires "Brake" = Output to brake lightsRed/Black wires "Indicator" = constant 36v powerRed/Black wires "Misc/Acc" = constant 36v power (cant really remember what the label here said)Red/Black wires "Charge" = Input from charging port *I dont like how thin these wires are and have my battery management system directly wired (AKA not using this controller for that feature)Green/Yellow wires = high speed mode (can be switch controlled or jumped)Larger Yellow/Blue wires = Motor (polarity can be reversed to change motor spin direction)Larger Red/Black wires = BatteryUsed in an old "Cruzin Cooler" the motor and throttle are upgrades from Ebay.Pros:Circa 15% upgrade in speedThis controller has not over-heated. Taken the cooler for various length trips, but no heat issues after 1 mile of riding. (Geared for torque, not speed and can move 200lbs at 20mph)The "high speed" mode being wired to a switch is fun, it does give noticeable gains in speed, and allows the cooler to be tamed down for younger riders.Misc/Acc wires are helpful for headlights or other accessories, but remember must be 36v lights!Cons:The connectors did not match up to my wiring harness, but all of the necessary wires are there. This is where things are slightly tricky if you are not experienced.MATCHING WIRES 100% BECAUSE OF COLOR WILL NOT WORK!The connectors are "labeled" however they are clearly translated into English and are slightly vague
