Please Help identifying underhood components

Well, I will admit that I'm really new to this and now thoroughly confused. I've gone down a big rabbit hole now trying to find articles and discussion on 1976 wiring. From what I can ascertain, and please correct me if I'm wrong, the '76 wiring is actually an upgrade from previous cars? I don't think fusible links are a bad thing to incorporate and the 50 amp stock alternator is good (it seems these big alternators are sought after on the older model cars).

Overall, I will keep trying to learn and do my research.

So will upgrading the headlights with a relay kit on a '76 really help take a load off my electrical system? How beneficial would it be? I did read a discussion about the slight difference in wiring and fusible links incorporated.

Why would Chrysler change out the wiring which worked so long for them on previous cars?

The main battery/alternator circuit which went thru the ammeter was not a good way to do it. That's why most of us with the older cars have bypassed the ammeter by adding a fat wire from the alternator directly to the battery (with an in-line fusible link.) Also, if you are switching to LED headlights, I do not think adding the headlight relay system is going to gain you anything. LEDs draw very little current as compared to the stock bulbs.
