I have made a break through with the wiring but only once I got a pen, a roll of masking tape, the colour wiring diagram and the ubiquitous mug of tea and sat down to identify the loose ends of wiring. Cable by cable and relay by relay the ends were checked off against the diagram and labelled. I now have only to work out a few of the finer points before securing the wiring loom to the frame. This will trigger me to hook up the available relays, switches and earth points. After that it is a question of a battery and a series of tests to ensure the major components work.
Pay day has come round again so I can have some more goodies. Fuel line this time and possibly a battery.
I have resolved to run the bike without a fairing so I have to work out how to modify the wiring from the RT version. I think it just a case of shorting the wires to bring the relays back inside the headlight shell. We shall see.
