New harness. Questions

Installing my new Blueprint 408 in the 72 Duster. All the wiring from the firewall forward I replaced with new harness from Classic Industries. My questions are. What are the two pictured connectors used for. One is coming from the wiper harness. The second is part of the lightning harness. The last is what is the purpose of the second blue wire with connector coming from the alternator. I have a flat back style alternator with electronic regulator . I’m replacing the factory automatic with a 4 speed. Thanks for any help.
