Correct, though the plastic connector is usually green, not blue. It is used to monitor the mixture control solenoid in the carb when setting the idle mixture. You connect a dwell meter to this terminal and read out on the six cylinder scale. Try to adjust the idle mixture screws to come as close to 30 degrees dwell as possible.
