2\) This harness cable is connected to the machine’s coin acceptor. It has two channels: the first channel uses yellow and white wires, and the second channel uses red and black wires.

3\) Try using the first channel **(yellow/white)** to connect the input and output on the harness using a 4-core cable from the device."

4\) Begin testing. If there is no response, check the input and output connections and the device. If all connections are correct but the issue remains, try switch to the second channel.
