As a last ditch effort to getting the horn working again, I bought new horn ring hardware and replaced the missing wire insulator.

Being too lazy (and frankly, stupid) to bother trying to thread that tinned wire tip through the tiny hole in the new plug, I just sliced it open like a hot dog bun.

It’s an insulated wire, anyway, so I’m not sure it’s even necessary. I’m just getting desperate at this point.

Throw parts at the problem if you’re not smart enough to figure it out!

Still no dice (or horn… there never were any dice).
I’m tired.
