Connection Guide
When connecting the open wires:
- Identify the exact wire-to-pin mapping for your cable batch.
- Connect power and ground first (OBD-II Pin 16 and Pin 5).
- Connect CAN High and CAN Low next (OBD-II Pin 6 and Pin 14).
- Connect any remaining lines only if required by your protocol.
Ensure all connections are secure and properly insulated. Incorrect connections can damage your AutoPi device or target system. Verify wire connections against your system's CAN bus documentation before powering on.
