After connecting the line, press the horn button, the horn will not sound, and the relay will not be pressed, which means that the blue line and white line are poorly connected. One line from the button connects to the blue line (or white line) of our wiring harness, the other line from the button connects to the positive line of the battery, and the white line (or blue line) on the wiring harness connects to frame 2. The air pump whines but the horn does not sound, which means the positive and negative terminals under the air pump are connected in reverse. The yellow wire should be inserted into the positive pole and the black wire into the negative pole. 3. The sound of the horn is not stable and sometimes it breaks. That is because there is paint on the frame where the black wire is grounded, which affects the normal power of the negative pole. As long as it's connected to a good ignition position, it's fine.
