I am rebuilding from the ground up. I have installed the main harness and the instrument light cluster and the switchgear.
In the headlamp I have light blue and white trace and orange with white trace that have no obvious connections (IMG_0012). all others are colour matched.
In the electrical junction box I have connected all the wires colour matched. The wires brown with white trace, light blue and white trace and orange with white trace have no obvious connector match.
There are three wires coming from the right hand switchgear that are black and each has two rectangular white boxes at intervals along each wire. There are no obvious connections apart from 2 on a black multi connector not used and also the green ground that attaches to the horn mount with the clear/black terminal cover.
The brown with white trace, light blue and white trace and orange with white trace in the head lamp are connected to the ones in the branch harness at the electrical junction box.
I am reluctant to fit a battery until I have established the connectors are correct, hence plea for UK wiring diagram. The ones that I have available are from Haynes manual (crap) and the US spec which don't really help.
