Backup Lights
When the Ignition Switch is in RUN, voltage is applied through the TURN-B/U Fuse to the Park/Neutral position and
Backup Lamp Switch. With the Transmission in REVERSE, voltage is applied to the
Backup Lamp, which is permanently grounded through Grounds G106 and G107. When voltage is applied to LT GRN (24) wire, the Backup Lamps are on.
