Okay, please help, this is doing my head in. LI headset wiring can anyone explain how to wire it up? The bulb holder looks like it’s made by Fisher-Price, I have taped together (temporarily) the wires I think go together and have posted pics of what wires I have. I have done a full rebuild and this is by far the worst bit without doubt.

Do you have the Sticky Manual? All the wiring diagrams are in there.

You'll need to give a bit more information.

What Series Li?
Italian or Spanish or Indian?
AC or DC? Do you have a battery?
Key switch or kill button?
What switch on the throttle side?
Have you replaced the loom?
If so is it standard or simplified?

General comments -

You will have wires from the loom usually -

Green - engine kill that shorts the ignition to earth either via the kill button or keyswitch - usually via a pink wire which goes to one of the screws on the gear or throttle rod supports.
Brown, purple and grey - these are usually live feeds and usually matched to corresponding colours from the switch(es)
Black - usually the is connected to the speedo bulb and to the tail light

the handle bar switch will usually have -

Red/ Blue - power to the dip and main beam - it doesn't matter which is which.
Yellow - power to the side light bulb.
Brown / purple / grey power into the switch

white to horn - pressing the button completes the circuit to earth.

HTH

BTW - if you replace the loom / switches with new from various sources there is no guarantee the colour coding is maintained as per OEM

Thanks for that Italian series 3 but electronic ignition .new switch so yeah not all colours don’t match wiring diagram .
Think sticky manual is next try ?

The latest one 3rd edition

The Sticky manual makes this a doddle. New loom around £30 and worth the investment on a rebuild.

Hi the top pic looks like an s2 light back an s3 one should have terminals for all the wires look at page 140 in sticky's book third edition

If you need any pic's photographed in Sticky's book 3, I can Whatsapp them.

I have ordered sticky’s book today from ebay . I need something that says the wire from point A is plugs into point B if that makes sense

Sticky's book has a comprehensive section of wiring diagrams in the back but you will need to order a new bulb holder/connector block as the one you've pictured is an S2 one not an s3

On the a to b thing a multimeter with beep mode is invaluable in working out where things start and end and in tracing eart faults.
