Relay/Voltage Regulator Question

[paulywood]

I'm running all new wires for my car. I found a couple of parts that aren't addressed in the diagram from American Autowire and I can't find the answers in my assembly manual. There is a part that I think may be the horn relay mounted on the firewall. Going from the drivers side it is past the wiper motor. Can someone confirm if it is indeed the horn relay? There were no wires hooked up to it and no horns in my car. (Anyone have a spare set of horns?

The 2nd is labeled a voltage regulator and it is mounted up by the front driver's side headlight. The assembly manual says voltage regulator, there are many wires that go to it, but the upgrade kit from AA doesn't address this in either the engine bay or front light kits. I was wondering if it was obsolete due to the upgrade and change to electronic ignition from points.

If someone can help I appreciate it!
