Looks like it has an LED showing state to help know what signal comes from the controller. Left on or off and right the opposite.
I would remove and reinstall that connector at both ends.
So the signal out of the controller is 5 volts. It connects to a stepper driver that drives the stepper motor. Loose wires at to stepper wouldn’t show up as a direction change.
Most likely the problem is in the pin1 wire.
