What are these?

Came from a friends 12/74 FJ40.

Thinking big guy is a Voltage Regulator? 4 blade plug. He says little guy came off the same harness.
3 blade on that one.

@ToyotaMatt ?

I can almost hear the theme song to Jeopardy playing in the background...The upper left one looks like a horn relay. I'm guessing that the other one is either a turn signal or hazard flasher.

Little guy looks like a horn relay, big guy looks more voltage regulator, take the cover off an look.

Wiget arm on the maniform, for sure and for certain.

Horn relay seems correct as he said horn stopped working when he pulled little guy.

Here is top off and back of big guy.

100% horn relay for the small one. Not sure on the other, aside from it not being on my 76MY.

Possibly resistors for the heater fan speeds? Similar ceramic, but directly on the fan motor on mine.

Dug around on the webs with your suggestion in mind and didn't really find any correlation.
I bet @65swb45 Mark would know.

Rest easy everyone, the big boy is the ignitor.
Wiring diagram to the rescue.

x2 ignitor, this looks like the two transistors.
