What are these two plugs?

"Go to?" The go to right where they are, that is the ballast resistor. One end comes from the key switch "in run" and supplies power to the ballast, which drops the voltage to the ignition coil. The wire taking off from the "key" "run" end taps off power to the voltage regulator IGN terminal.

The other end goes to the coil, and the extra wire comes from the key during cranking, and feeds full battery voltage to the coil during that time.
Very informative, thank you
