There is no dedicated circuit that increases the idle when the A/C goes on. What does happen is the idle ECU controls the idle speed and when it senses the idle try to go lower from an increased load (the A/C, the cooling fans, the alternator, headlights, rear defogger) it compensates by telling the idle motor to increase the idle to keep the motor at 775 RPM + or - 50 RPM. It also increases the idle when the motor is cold. Look over D:05:01 to :04 in the Workshop Manual. Of course this is assuming the idle motor circuit is properly set up and the brass screws are closed and there are no vacuum leaks.
