WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The stoplamp switch is supplied battery voltage through circuit 10 (LG/RD). When the brake pedal is pressed, the stoplamp switch routes voltage to circuit 511 (LG). Circuit 511 (LG) supplies power to the multifunction switch and the high mounted stoplamp. The multifunction switch internally routes the power (when in the NEUTRAL position) to circuits 9 (LG/OG) (LH stoplamp) and 5 (OG/LB) (RH stoplamp). Circuits 9 (LG/OG) and 5 (OG/LB) are routed through the CJB and then on to the LH and RH stoplamps accordingly.
