- When ground is received through circuit (L/G)/(Y/V) and powered through (GY), the LH/RH exterior mirror will operate RIGHT.
- When power is received through circuit (GY/O)/(V/O) and grounded through (GY), the LH/RH exterior mirror will operate UP.
- When ground is received through circuit (GY/O)/(V/O) and powered through (GY), the LH/RH exterior mirror will operate DOWN.
