Bob Gibbons' 1964 LHD
Hover over a wire to confirm the colour
Note: Shown as a physical earth i.e. a single wire to the bulb holder on RHD and Mk1 LHD schematics, as on this picture of a 1964 LHD from Bob Gibbons, but a wired earth on North American Mk2-on schematics.
Nevertheless this replacement UK harness has a wired earth Photo: Terry Cooper
It also has spades on the wires that go to the switch - as does Bob Gibbons' switch above - but the suppliers I have checked all show switches with screw terminals, as in this example from Leacy.
