Where is the BYD F3 fuel pump fuse located?

[MacBrooke]

BYD F3 fuel pump relay is located on the wiring harness assembly, not inside the fuse box. The wiring harness assembly is positioned below the steering wheel on the left side. More details are as follows: 1. Function: The fuel pump relay primarily serves to amplify signals, allowing a very small current to control a high-power circuit. It also expands the control range. When the signal reaches a certain threshold, it can switch, disconnect, or connect multiple circuits simultaneously based on different contact group configurations, achieving automatic switching. Another function is to adjust the fuel pump's activation and deactivation to ensure the engine operates normally. 2. Principle: This control circuit can alter the fuel pump's power supply line through the fuel pump relay based on changes in engine speed and load, thereby controlling the fuel pump's operating speed.
