I thinkthat maybe the plug in the last photo is for A/C compressor power. The ac harness is separate from the main harness and can be removed separately if you dont have a/c.

BTW, 67-72 harness are pretty much the same depending on engine type (6 cyl vs sbc vs bbc) for 67-72. Also, the larger gauge red wire with the ring terminal and rubber boot on it on your harnesses connects to an external regulted alternator the same way it connected to the internally regulated one.
