Interior Illumination Operation
When the lighting switch is moved to the side lamps or headlamps position, the feed passes through the switch contacts and is connected to the passenger compartment fusebox on an R wire. The feed passes through fuses 11 and 33 in the fusebox.

A feed from fuse 33 is connected on an RO wire to header C0759.

A feed from fuse 11 is connected on an RB wire to header C0288 LHD/ C0286 RHD.

From header C0759, RN wires supply power to the interior illumination bulbs, with the exception of the glove box switch. The glove box switch is supplied on an RB wire to the switch and an R wire from the switch to the glove box lamp.

From header C0286, RB wires pass through headers C0295 and C0724 and supply power to the remaining interior illumination bulbs.

All of the bulbs are earthed by B wires, with the exception of the rear window LH and RH switches These switches are connected to the window lift isolation switch on SG wires which is then connected to earth on a B wire.

The instrument illumination dimmer rheostat receives a supply on an RO wire from header C0759. The rheostat supplies a reduced power feed on an RN wire to the header C0759. The rheostat is earthed on a B wire to earth header C0018, via header C0760.
