Refer to Wiring Diagram Set 90, Turn Signal/Stop/Hazard Lamps for schematic and connector information. See: Diagrams/Electrical
Diagrams/Diagrams By Number
Normal Operation
When the brake pedal is applied, the stoplamp switch routes voltage to the Smart Junction Box (SJB) and the high mounted stoplamp through circuit
CCB08 (VT/WH). When the SJB detects the brake pedal is applied, the SJB provides voltage to the LH and RH rear stoplamps through circuits CLS18
(GY/BN) and CLS19 (VT/OG). Ground for the all the stoplamps is provided through circuit GD110 (BK/WH).
The SJB fuse 6 (20A) supplies voltage for all the stop and turn lamps.
