Stop Lamps

The STP HAZ fuse in the instrument panel fuse block supplies battery positive voltage to the normally-open stop lamp switch.

When the driver presses the brake pedal, the switch contacts close and the stop lamp output signal is applied to the CHMSL and to the hazard warning switch. The stop lamp signal is applied from the hazard warning switch to the turn signal switch.
