Backup Lamps

WARNING: This page is about a different car, the 2002 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

The B/U fuse in the underhood fuse block supplies battery positive voltage to the park neutral position (PNP) switch. When the driver places the gear selector lever in the REVERSE position, the current flow is from the PNP switch to the backup lamps. The backup lamps are grounded at G302.
