Backup Lamp: Description and Operation

When the Ignition Switch is in "OFF" or "RUN," voltage is applied from the PRNDL Fuse to the Transaxle Position Switch (Automatic) or Back Up Lights Switch (Manual). With the Transaxle in "REVERSE," voltage is applied to the LH and RH Back Up Lights, which are permanently grounded. When voltage is applied to CKT 24, the Back Up Lights are on.
