Thank you both - I'm guessing the previous owners (a very large family of rats) did more work behind the dashboard . After 6 months I'm still finding poop where I least expect it !
Still trying to get my head around the circuitry without unraveling the loom - would the black wire
here at the fuse box be a direct connection to the positive on the horn. I've tried a circuit tester but there was no reading so I suspect not (or else it was gnawed)
I guess, what I'm trying to ask is how to trace the purple/black electrical wire that leads from the indicator stem as I'm not sure how that gets to be the
black wire that connects to the actual horn.
Out of curiosity - could anyone tell me what those 2 unmarked switches do ?
