292 Engine harness HEI conversion

[DoubleL]

Hey guys I am almost through with the rewiring of my truck but am having one more question. I converted my old "light" harness to HEI. Now I am installing a new "gauge" engine harness. I am either getting too tired or confused but I can't figure this out. I am showing my connectors for my new harness. Can anyone tell me which wire goes to what and what I need to modify it. I know in the first pic the one slotted connector goes into my temp sender and the other would have went to my old coil. I think the second pic all goes to the starter - ground on the left terminal and other two on the right. But I think I can eliminate some of these when I go HEI. Finally the last pic...do I need to add a new terminal for my new 12 gauge HEI wire? Thank you!

By the way my underdash harness was replaced also.
