Two other points:
- Alternator-equipped cars will not run with the battery disconnected;
- Place an appropriately-sized fuse on the battery end of that large wire between the alternator and battery.
Side question: why are you going to all the trouble of re-wiring this car? The factories usually do a damn fine job of it. Secondarily, if this is an IT car you're prepping, making these changes - even for "simplicity" - is likely contrary to the rules (though the new ECU wiring rules make that a gray area).
It's certainly contrary to your well-being and sanity... - GA
