Backup Lamp: Description and Operation
BACKUP LAMPSThe backup (or reverse) lamps have a path to ground at all times through a takeout and eyelet terminal of the rear lighting wire harness that is secured by a ground screw to the base of the right D-pillar behind the quarter trim panel. The backup lamps receive battery voltage from a fused ignition switch output (run) fuse on the back-up lamp feed circuit only when the backup lamp switch (manual transmission) or the Transmission Range Sensor (TRS electronic automatic transmission) is closed by the gearshift mechanism within the transmission.
