Stop Lamps

Battery positive voltage (B+) is applied at all times from the underhood fuse block STOP fuse to the stoplamp/BTSI switch. When you press the brake pedal, battery positive voltage (B+) is supplied via CKT 20 (LT BLU) through the stoplamp/BTSI switch and the rear fuse block to the high mount stop lamp and tail/stop lamps.
