Well, these are some pics I shoot for help to identify the motor controller on the board a RC Car.
The big red and white wire should be to the wheels motor.
The two spots that show Red and white, should be the wires to the motors.( not the ones that are linked by the line with the word yellow) I think those are the right wires. However made this board didn't name the wires with things like GND, or PWR, they all say colors.
