Depending on where u put the motor. If ur sprocket are facing your right side then you are good. But if your sprocket is on your left side. Then you switch some wire around. The big yellow wire and the big blue wire needs to be switch so itll be yellow on blue and blue on yellow now you must switch the wire from your sensor plug meaning the plug with small wire with red,black,yellow,blue and green. Switch the yellow and the green so yellow be with the green wire and green wire with the yellow. And thats how you reverse the motor
