I resume this post since i stripped my bike completely and now, after replacing carb, tank, toolbox, and many other parts that im not listing here, i am taking care of the electrics. I replaced the whole cable mess that i found on my bike, which was assembled without any logic and that caused me many problems during the summer...
I started with the wiring loom; i purchased a simplified version from bgm. I am following the diagrams taken from sticky's book (aka the bible) that has helped me a lot during all this time. I am keeping the light switch and the ignition switch that were fitted on the bike cause maybe i can still use them if i manage to match the colours correctly.
From right to left:
1) In the green slot of the headset i put the green exit from the wiring loom and the green from the ignition.
2) In the yellow slot (that on the diagram that i'm following is orange instead) i put the orange from the ignition and the pink from the light switch.
3) Following the diagram in the purple slot there should be the purple coming from the ignition and the grey coming from the loom (or brake pedal

) . But my ignition has no purple (has
blue instead!) and my loom has only 3 exit: black, green and brown. Brown goes to the regulator, green to the green slot in the headset junction and black i suppose goes to earth (in the black slot on the extreme right of the junction). That's where i put it.
4) In the brown slot there's brown coming from the loom and brown comin from the ignition that is splitted in 2 parts, the second part should be going to the horn but it's too short as you can see from the picture 2 (in the pic 2 you see also the blue coming from the ignition that maybe replaces the purple?). In the pic 4 you see all the wires coming from the ignition, on pic 1 you see the diagram and on the 3rd a close up of the slots.
Can anyone help me throu all this?? IS there a chance to match the colours correctly?
Any help super appreciated.
