[0022] The power terminal 1 is electrically connected with the input end (5a, 5b) of the emergency starting switch 5, and the power-on end T15 and the starting end T50 of the ECU connector 3 are respectively electrically connected with the output end (5c, 5d) of the emergency starting switch 5. The emergency starting switch 5 is a manual switch, and when the emergency starting switch 5 is actuated, the power terminal 1 is conducted with the power-on end T15 and the starting end T50 of the ECU connector 3.
[0023] The power terminal 1 is connected with a power supply, which is generally a DC 24V power supply. The instrument connector 4 and the ECU connector 3 are respectively connected with the interface of the instrument and the ECU.

The functions of the power supply harness are described below in the use state. When the instrument is normally working, the power supply supplies power to the ECU and the instrument. The instrument inputs a power-on signal to the working power-on switch of the ECU and inputs a starting signal to the engine ignition starting switch of the ECU. When the instrument fails to send signals to the working power-on switch and the engine ignition starting switch of the ECU, the manual control emergency starting switch 5 is actuated, the power terminal 1 is conducted with the power-on end T15 and the starting end T50 of the ECU connector 3, and the power supply supplies power to the working power-on switch and the engine ignition starting switch of the ECU through the emergency starting switch 5, so that the engine is running. When the engine needs to be stopped, the manual control emergency starting switch 5 is actuated to realize normal stopping of the engine.
[0024] As shown in Figure 2 , specifically, the emergency starting switch 5 includes an emergency power-on switch 53 and an ignition starting switch 52.
