Headset wiring

[gizmo]

I've got this written down but still confusing myself. 12V a/c. Mb loom, casa ignition. To horn I have white from light switch and red from loom. Ignition a brown has 2 feeds. What does the long one go to as it's long enough to go to horn. Also the purple. Does it go with red from loom. Thanks

If the red from your loom is a power feed like Brown yes it will go to Horn , Most ignitions have a brown feed that goes to the horn as well so that can be capped off if you use the red from the loom , The purple from the ignition ? i believe bridges with the browns in the headlight block

Thanks Toddy, annoying thing is I've fitted 2 of these before but don't remember the long wire
