WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

The smart junction box (SJB) monitors the input from the instrument panel dimmer switch by sending a voltage reference signal through circuit 1403 (BK/WH) to the instrument panel dimmer switch. The return signal is sent through circuit 1036 (BN/WH) back to the SJB.
