As I received it, the W/NG has very little wiring remaining. This is the wiring diagram I will use, but it will need a brake light and a dip switch adding:

I know that the W/NG used coloured cotton braided cable, because it is still there and there is no evidence of the rubber cable markers that the SQ4 wiring harness was fitted with. This must have changed during the war, as the W/NG workshop manuals show pictures of the headlamp instrument panel with banded wires.

I've bought some cotton braided cable from https://www.vintagecarparts.co.uk/. Looks fab:
