Day/Night Mirror
The day/night mirror receives power from circuit L10 when the ignition switch is in the RUN position. This circuit is protected by a 10 amp fuse located in cavity 15 of the fuse block.
Circuit Z4 provides ground for the day/night mirror.
When the back-up lamps switch CLOSES, circuit L1 provides a signal to the day/night mirror. The day night mirror turns OFF when the vehicle is in reverse.
