Mostly good ideas and suggestions here. The bulkhead connector on the firewall needs to be closely inspected, cleaned and packed with dielectric grease (a bit controversial for some).
Dual field alternators for those that don't have them helps a lot with dimming lights at low idle. Mopar alternators in general are not that great at putting out significant amperage at idle, but there are alternate alternators that can and don't look that bad.
I've attached a pic of my E-Body alternator swap that puts out 115 amps at idle, as I added a lot higher amp loads to the car. I should say it's capable of up to 115 amps if needed, as it only puts out what the demand is at a given accessory setting. My A-Body uses the factory Magnum style alternator driven by the stock'ish serpentine belt system. It handles my 2 Hellcat fuel pumps, Dual Spal fans and A/C with no issues.
Running a larger, fused wire/cable from the alternator output stud to either the started relay lug or other 12V distribution lug is a good idea.
Using such a 12V distribution lug to feed high load circuits with relays and fuses has worked well on my Mopars. It keeps the high amp loads out of the bulkhead connector. I swapped to interior/exterior colored LED's and moved my headlight and A/C main feeds to an underhood and/or trunk mounted distribution lug. I also had my Amp gauge converted into a volt meter. Only low amp draw circuits pass through my bulkhead connector now. It is not difficult to hide additional relays/fuse blocks if you want to keep things stock appearing.
