Hi Dennis,
Here's the Lucas system of colors
Black B Earth, ground
Brown N Unfused--always a hot wire
Purple P Fused but always hot
White W Unfused-hot when ignition is on
Green G Fused- hot when ignition is on
Blue U Headlamp supply-not fused
Red R Parking & Tail lights, not fused but can and should
be for safety
Yellow Some OD circuits
There is a tracer code too
Red-white RW Park, tail as above. W tracer leads to panel
lights
White-black WB W is ignition, unfused. B is coil-distrib
connection
Blue-Red UR U is headlights, R is for low beams
I think there is more to this coding, and that John Twist charted it all
in a Moss Motoring issue. When I find it, I'll post it.
