3 pins conduct continous power and digital control signal(LIN-bus), the drive signal for mirror adjust are produced locally inside the mirror. The 5 pins conduct analog drive signals for the mirror adjust motors, and heat. The analog signal originates from the mirror adjust switch in the door.
Without vehicle option code 313 or 430 in your vehicle options list you have 5 pins, with you have 3 pins.
