Installing one wire alternator

I’m reviving this thread because I need a little help. Working on a ‘1974 Dodge W200 truck.

I’m installing an internally regulated Denso 60 amp 3 wire unit. I’m kinda following 2 sets of instructions.

I have a 6ga wire from the alt output going to a fuse as you can see on the firewall, and from there I’ll be going to the starter relay battery lug. I think ANDY AR Engineering’s instructions call this a “Shunt” to keep the whole load going into the firewall on the original black 10ga alternator wire to bulkhead.

Now can I still place this same 10ga black wire on the output stud of the new alternator along side the other heavy 6ga? (this one goes through the bulkhead)

(this is the old alternator output wire going to bulkhead, which then connects to many things like ignition switch, high & low beams, ammeter, fuse panel) Because of all this I thought it would be a good idea to also use this wire. ?

The American Wire wiring harness gets rid of all those extra components like the voltage reg, ballast, and resistor in the original electrical system. I replaced our entire wiring system with one, see our schematic - very simple.
