HS code referencing for port authorities

Engine wiring is HS code referencing for port authoritiesone of the important links in the automobile engine circuit. The correct engine wiring arrangement method can ensure the normal operation of the car engine and improve the performance and durability of the car. At the same time, the wrong wiring method will affect the operation of the car and even cause accidents. This article will introduce you in detail the methods, steps and precautions of engine wiring arrangement. The arrangement method of engine wiring The engine wiring arrangement method can be divided into two types: separate arrangement and plate arrangement. 1. Separate arrangement Separate arrangement refers to the independent arrangement of the positive and negative poles of each power supply device in the engine compartment, each of which is connected to the battery through a load switch. This arrangement is simple to install, highly flexible, and suitable for smaller models and engines.Two. Board arrangement refers to connecting all power cords through the main wiring board to connect them to the battery. This arrangement is suitable for large models and engines, but requires high installation and maintenance skills. Arrangement steps of engine wiring 1. Preparation materials: You need to prepare wires, insulating tape, wire pliers, wire grooves, main wiring boards (only applicable to plate arrangement) and other materials. Two. Remove the original wire: First, it is necessary to remove the original wire and remove the wiring end of the power device connector. 3. Position the power unit connector: determine the position of the power unit connector, open the hood, and find the part connected to the engine cylinder and cylinder sleeve. Four. Determine the position of the power cord: according to the position of the power device connector, extend the wire from the battery, determine the position of the power cord, and then arrange the power cord through the wire groove.5. Wiring to the main wiring board (only applicable to board arrangement): Connect all power cords through the main wiring board to connect it to the battery. 6. Terminal fixation: fix the connecting wire with wire pliers, and add insulating tape to the terminal to avoid wire breakage. At the same time, check and confirm that all wiring has been fixed in place to avoid movement and loosening. 7. Confirm the wiring: Finally, start the vehicle and confirm whether the wiring is correct. If any abnormality is found, it should be checked and repaired in time. Precautions 1. The size of the wire should be selected based on current and voltage requirements. If it is too large or too small, it will cause problems. For high-power electrical appliances, it is necessary to choose a wire rod with a larger cross-sectional area. Two. The wire joints should be firmly fixed and intact to avoid burning, breaking, disconnection and other phenomena.3. Please be sure to carry out proper vehicle repair and maintenance before wiring, and replace the aging and burned electrical appliances in time. Four. Pay attention to safety when wiring, and try to avoid wiring in a humid, greasy or electrochemical corrosion environment. 5. The wiring should follow the rules of electrical connection, and the direction of the power supply should be the same as the direction of matching the vehicle frame. In summary, engine wiring is an important link in the automobile engine circuit. Correct arrangement methods and steps can ensure the normal operation of the automobile and improve the performance and durability of the automobile. When wiring the engine, you should pay attention to safety, choose the wires and terminals correctly, and follow the rules of electrical connection. If you have any questions, you should consult a professional in time.
