About these circuit diagrams
Where they come from
These are the factory wiring diagrams (电路图) for the China-market Aion V, 2nd generation, in two editions: the 2024 model and the 2025 refresh. There is no wiring manual for the export (Sri Lankan) car.
How they differ from a Sri Lankan car
- Left- vs right-hand drive. China cars are left-hand drive; Sri Lankan cars are right-hand drive. Wire colours, pin numbers, fuse ratings and the circuits themselves carry over, but anything about position can be mirrored: "driver side" in these pages is the right side on a Sri Lankan car, and parts near the steering column, pedals, wiper motor and the driver side of the dashboard (and their connectors and ground points) may sit on the other side.
- Self-driving hardware. China cars can have the L2+ self-driving version with lidar, the ORIN computer, stereo and long-range cameras and extra radars. Sri Lankan (export) cars have the simpler set-up: windscreen camera, front radar, rear corner radars and panoramic cameras. Pages for the China-only hardware are tagged China only.
- A mix of both editions. The export car shares some equipment with each China edition (for example the boot 12 V socket and auto-dimming mirror of the 2024 wiring, and the heated steering wheel of the 2025 wiring).
How to use the two editions
- Pages that are the same in both editions are shown once.
- Pages that differ have a 2024 model / 2025 refresh switch and a "What changed" list. Your choice is remembered on every page.
- Pages that exist in only one edition are tagged "2024 only" / "2025 only".
- The final check for your own car is its fuse-box lid label and the fuse ratings: see the fuse-box pages.
Missing pages
About 45 location maps (where connectors and ground points sit on the car) could not be copied: the source website fails to load them for everyone. The connector and ground-point pages still give pin tables and most show a small location picture.
