What do I need to do my electrical system in my dart.

Will this wiring method kill the alternator? It looks like the master kill switch will kill battery power but not kill the alternator.

I wonder if there's an advantage of going this route (above) vs. the one commonly posted on this site originally from @crackedback Rob. Looks like the one above eliminates the CD relay.

Edit - I guess the advantage of running the CD relay is that once the cutoff switch is thrown, it kills all power forward to the car. Using the MAD method shown above, the alternator line is always hot.

Yes, the Crackedback wiring looks like a better idea. The one I posted was from over 20 years ago and used on a D250. Not so many power using items back then. And it was just a basic "trunk" battery system and all under hood and dash wiring was on a different wiring diagram chart. Justin's truck relays.jpg
