The speed control actuator communicates through the SCP network, circuit 914 (TN/OG), and circuit 915 (PK/LB), with the instrument cluster to illuminate the speed control indicator lamp. When the speed control system has been turned on and is ready to process driver commands, the speed control switches provide a resistance, through circuit 151 (LB/BK), and circuit 848 (DG/OG), to the speed control actuator.
