What Are These Relays/Switches on the Underdash Harness?

Not disagreeing, but I don't recall an emergency flasher in my 69 Dart Custom, but that was long ago. I also don't recall a time-delay on the lights, but might not have had that option.

I recall a similar-looking component as #1 in my 64 Valiant. I suspect it has to do w/ the powered convertible top, perhaps an over-current breaker. That wire harness was pretty hacked by gomers.
