Stop Lamps

WARNING: This page is about a different car, the 2002 GMC Savana Special, 2002 GMC Savana Camper Special, 2002 GMC Savana, and 2002 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.

The STOP LPS 20 A fuse 1 in the IP 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 switch signal circuit supplies voltage to all vehicle stop lamps. The stop lamps are grounded at G400 and G401.

For trailer wiring, a separate stop lamp circuit is connected through the multifunction switch to the trailer wiring harness.
