then as far I can tell by the instructions, this will be the new setup at least for main starting and charging circuits

NOTE... I DON'T KNOW IF ALT WIRE AND IGN SWITCH WIRE ARE FUSED OR NOT, being simple spliced in to batt buss bar. I simply ilustrated like they are fused, but if they are the shgould be BIG CAPACITY FUSES... 40, 50 or 60 amps fuses.

remember this is just what I supose it is without have in hands the fusebox

I'm based on how it works any Mopar Body ( except those with starter solenoid with coil ballast bypass provision, on lates 70 )
