Navigator 4WD V8-5.4L VIN 5 (2006)
I4-I5
Normal Operation
When the brake pedal is applied, the stoplamp switch routes voltage to the high mounted stoplamp and the multifunction switch through circuit 511
(LG). The multifunction switch then routes the voltage to the central junction box (CJB) through circuit 9 (LG/OG) and circuit 5 (OG/LB). The CJB
then routes the voltage to the LH stoplamp and RH stoplamp through circuit 9 (LG/OG) and circuit 5 (OG/LB) respectively.
