The smart junction box (SJB) sends a pulse width modulated (PWM) voltage to the steering wheel controls through circuit VLN04 (VT/GY) to the clockspring. The PWM signal passes through the clockspring to circuit VLN04 (VT/GY) to the LH and RH control switches. Ground to the clockspring is supplied through circuit GD116 (BK/VT). Ground from the clockspring to the LH and RH steering wheel switch is supplied through circuit GD165 (BK).
