Do I really need the wire from the alternator to the bulkhead connector?

You have a custom setup. You need to come up with a wiring strategy for supplying power and distributing it to the electrical equipment. Make list of the power needs for each of the items. Some will be variable, so for those list the range. Then make drawing of how the electricity will get from the power supply to the distribution point for various circuits.

Hey Mattax, this is some quality advice for sure. I'm good an imagining and conceptualizing these things, but it would help to put a wiring diagram on paper and see it. Still just conceptualizing, here's what I'm thinking about the electrical equipment and the power for each:

Headlights, fuel pump, starter relay power, and EFI system will be powered from the relay box. Relay box connected to the alternator and battery.

Interior lights, side markers, taillights, radio, cigarette lighter (i.e. phone charger), and starter relay trigger powered from the connection that goes into the bulkhead terminal.


So there will be a lot less power going to the bulkhead terminal.

I'll go through those other links you posted when I'm not on the clock at work.

Thanks!
