This is my layout. I'm using the Longacre 3 in 1 ignition and start switch. The actual engine wiring will be another explosion, but conceptually you see how the layout. I have a mechanical fuel pump and no ECU (carbs) so mine will be very simple. Just the starter, alternator, auto choke, ignition, electrical fans, and ground. I'll be using relays for each of those.

I ran a separate switch to turn on the accessories. This is necessary to manually shut down the accessories to reduce current draw when the starter is cranking. Otherwise you'll have to use an inverter and it gets complicated really quickly. I'll be running relays for the accessories as well.

Nissan designed several accessories to be constant on, like horn, hazards, headlights, brake lights, parking lights, etc. I don't really like this because I tend to leave my lights on. I wired all these to turn off with the accessories switch, which goes out with ignition OFF so I don't have to worry about draining the battery.

The only constant on power source I have is for the radio presets. You will need this for your ECU as well.
