What are these?

These are behind the drivers side headlight, next to the radiator. Anyone know what these are for?

The Large Rectangular piece appears to be the Horn Relay.. the other is some type of capacitor

Horn relay and capacitor for damping alternator noise...I think.

I'd also guess horn relay with noise suppression. Ford used a three wire plug on their relay circuits and this one is obviously a PO installed with crimp connectors. I'd be curious as to where those wires go from the relay.

Are those capacitors still available from Ford, by chance?
