WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

The smart junction box (SJB) sends a pulse-width modulated (PWM) voltage to the dimmable components through circuits VLN04 (VT/GY). Ground for the illumination source(s) is supplied through circuits GD116 (BK/VT), GD126 (BK/WH) and GD139 (BK/YE).
