Battery cables and disconnect wiring?

Getting ready to wire up my 89 Mustang LQ9. Battery is mounted in rear with a disconnect switch. Does this wiring diagram look ok? I'm ground to body and also running a 1/0 ground to engine block. 1/0 positive wire from batter to disconnect then from disconnect to starter. 4 gauge from back of alternator to starter. 4 gauge from back of alternator to a junction post to power the factory ignition wires. Factory ford starter trigger wire will be wires to GM starter.

The disconnect switch will not kill the car once it is running without routing the alternator wire back to the battery's pos. post if you are looking to go racing.

Here's the diagram that I'm working from, hopefully this is helpful. (MDS = master disconnect switch, aka battery disconnect switch).
