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.
Voltage is supplied to the reversing lamp switch through circuit CBP18 (GY/OG). When the transaxle is placed in REVERSE, the reversing lamp switch routes the voltage to circuit CBP12 (GN/WH) to the reversing lamps.
