1. All the circuits connected to the motor control end and the motor end use a solid core twisted-pair shielded wire to preferentially satisfy the three pairs of differential signals of sin, cos and ref, respectively, using a set of twisted pairs to meet the line color requirements.

2. In the circuit where the whole vehicle end is connected with the motor controller end, the whole vehicle CAN and the debugging CAN each use a solid core twisted pair shielded wire.

3. All wires used in the wire harness can reach -20°C-105°C for long-term normal operation.
