Ignition start wiring

[Katfish]

Want to verify this will work.  I've seen other threads, but just couldn't wrap my head around it.
I have the Mopar harness, but it seems it will be easier, and less wiring to use the stock start circuit and relay.
Will motor start and run without the Mopar harness wires connected?

It looks like it will work. I'm out of town until the 25 so I can't pull out the diagram I used.
I can say I would run the alternator wire direct to the battery  with fusible link, and the main power to starter from the battery as well. then like the rest of what you have in your schematic. To integrate the rest of the car electrical I ran the original alternator wire that goes into the bulkhead to the PDU I'm assuming that's power distribution unit with a 40 amp fuse.
Hope this makes sense and helps.
