Searching for 12v switched power after ditching ballast and installing aftermarket electronic ignition

I don't really understand what you mean with J2 and J3 going to a relay. Draw a diagram.

Not sure why you need a fuse block for the ignition on wire, or a tach. CD deck I would power from the auxilery buss if there is room in the OEM fusebox. Alternately have it trigger a better connection using a relay and fuse. It doesn't need to be on during start and the battery is already under lots of load.
With an electric fuel pump, yes it will be best to be on during run and start. How much current it draws at 12 and 14.5 V will determine if the wiring is sufficient. There's really no reason to use one with a carb. EFI is another story.

The joining of blue and brown mentioned earlier in this thread to create 12v switched power, that joint, is going to be the feed for a relay that sends power to this aux fuse block. But the more I think about it, I guess that relay is not a replacement for a fusible link or fuse. Also, im the last guy who could draw a diagram for this lol.

And technically, I dont need it. But I want these added accessories to be in one place, clean, and easy to access....I cant stand crawling under a dash, and I also want something that can allow future growth for any additional circuits in the future.

Many reasons to use an electric pump with a carb, but thats not important right now.
