Stop Lights

Battery positive voltage (B+) is applied at all times through RH rear junction block HAZD/STOP LPS Fuse to the stoplamp/BTSI switch. When the brake pedal is pressed, battery positive voltage (B+) is applied through the stoplamp/BTSI switch to the tail/turn/stop lights and the Center High Mounted Stop Lamps (CHMSL) causing all stop lights to light.
