Weird horn issue for 71

[jonny0666]

So I have a 71 roadrunner. The horn only works continually in ACC not in Run. Run works sporadically. Any advice??

Horn should be wired through a relay that is hot all the time not off the key. Sounds like you are wired wrong. I would correct that first.

Fair enough, let me work on that.
