Passenger car circuit wiring modularization structure

A passenger car circuit wiring modularization structure is composed of a connector (1), a wire outlet protection part (2), an integrated circuit (3), a cable inserting coil (4) and an execution piece segmentation wire harness (5). The connector (1) is installed on the left side of the front of a passenger car. The integrated circuit (3), the cable inserting coil (4) and the execution piece segmentation wire harness (5) are installed in the front middle of the passenger car. The integrated circuit (3) is connected with the cable inserting coil, the execution piece segmentation wire harness and the connector. The wire outlet protection part (2) is installed at the execution piece segmentation wire harness to the middle of the connector. The integrated circuit (3) comprises a non-bus wiring module and a bus node module. The passenger car circuit wiring modularization structure is high in integration degree, the quality control deviation caused by traditional manual wiring is reduced, the modularization integrati
