Stop Lights

Battery positive voltage (B+) is applied at all times from underhood junction block STOP Fuse to the stoplamp/BTSI switch. When the brake pedal is pressed, battery positive voltage (B+) is supplied via CKT 20 (LT BLU) through the stoplamp/BTSI switch and the rear junction block to the Center High Mounted Stop Lamps (CHMSL), the RH and LH tail/stop lamps, and the trunk lid tail/stop lamps causing the stop lamps to light.
