LUCAS WIRING CODES
BROWN - Direct, un-switched, un-fused supply from the battery.
Usually wires to alternators, dynamos, control boxes and ignition
switches etc. Always live and often carrying heavy current.
YELLOW - Sometimes used as an alternative to Brown on older
cars. Also used on solenoids and overdrive switches.
PURPLE - Direct, un-switched but fused supply from the battery.
WHITE - Un-fused supply from the ignition switch to Fuel pump,
coil.
GREEN - Fused supply switched via the ignition switch. Indicators,
stop lights, instruments, wiper motor which only work when the
ignition is on
RED - The main colour for rear and side lights
BLACK - The usual colour for wires from components to earth
points on the body or chassis
BLUE - The main colour for front lights - Headlamps and
Spotlamps.
These refer to the main colour of the wires.
Many wires have a
second, thinner (tracer) colour.
This is used to identify the specific
purpose of the wire. E.g. Black/Green to Radiator fan motor
