Having trouble getting the horn to work. Recently fitted a customised WiredbyWilson front loom, and everything else seems to work. Here's the situation:
Horn itself is okay - connect it to 12V and earth and it works.
No break in the purple/black wire - if I join the purple and purple/black wire from the indicator stalk, the horn works.
All other functions on the stalk seem to be fine. No fuses blown as far as I can see.
Naturally this would point me towards a faulty horn press on the stalk. However, I've tried a new stalk and get exactly the same thing.
Confused now!
