Vanity and Rear View Mirror
With the ignition switch in position I or II the feed from fusible link 7 passes through the auxiliary circuits relay contacts and is connected on a WG wire
to the passenger compartment fusebox where it passes through fuse 15. From fuse 15 the feed is connected on an LGW wire, via header C0286
LHD/C0291 RHD and splice joints A132 and A138, to the interior mirror and the LH and PH vanity mirrors.
When the cover on each vanity mirror is lifted, the bulb will illuminate. The LH and PH vanity mirrors are connected on B wires to earth headers C0706
and C0707 respectively.
The power supply from fuse 15 in the passenger compartment fusebox supplies power to the interior rear view mirror. The automatic dip function of the
mirror can be selected on or off on the mirror. The mirror is connected on a B wire to earth header C0706.
When reverse is selected, the feed from fuse 25 in the passenger compartment fusebox passes through the reverse switch contacts and is connected, via
header C0287 LHD/C0294 RHD to the interior mirror on a GN wire. This supplies power to the interior mirror and changes it from its dipped to normal
condition when applicable.
The interior lamps operate independent of the ignition switch position and can be operated manually or automatically when a door is opened.
