Electrical & Wiring

Wiring harnesses and electrical distribution systems are the nervous system of BYD electric vehicles, routing power and CAN-bus data signals between every electronic module in the vehicle. This category covers instrument panel wiring harnesses, floor harnesses, ceiling harnesses, door harnesses, front cabin harnesses, front cabin power distribution boxes, starting batteries, battery terminal harnesses, antennas (4G/GPS, detection), SIM card readers, in-vehicle network terminals, electronic smart keys, USB charging connectors, combination switches, and charging vehicle sockets for BYD Atto 3, Dolphin, Sealion 7, and Denza D9. Replacement harnesses must match the exact connector types, wire gauge, and shielding specifications of the original to prevent signal interference with high-voltage drivetrain components.
