RH Headlamp Levelling Motor
Fuse 20 of the passenger compartment fuse box (C0581) provides a feed to the RH motor 
(C0070) on an RO wire. The headlamp levelling switch (C0093) provides a feed to the RH 
motor (C0070) on a UY wire. By comparing the voltage supplied by fuse 20 with the voltage 
supplied by the switch, the motor moves the headlamp to the required position. The motor 
(C0070) is earthed on a B wire.

DESCRIPTION AND OPERATION
DEFENDER 02MY 4.47
When the fog lamp ECU (C1724 on LHD, C0543 on RHD) receives a feed from fuse 26, it 
provides a feed to the fog lamp switch (C0064 on LHD, C1741 on RHD) on a BS wire. When 
the fog lamp is pressed, the switch contacts close, and a momentary earth path is created 
on a B wire. Sensing this earth, the fog lamp ECU (C1724 on LHD, C0543 on RHD) provides 
a feed to the following on RY wires:

The tell-tale LED (C0064) located in the fog lamp switch
