Non-Dimmable Illumination
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
When the ignition switch is in the START or RUN positions, the delayed accessory relay provides voltage from the SJB to the non-dimmable components.
